    Default Two queen hive and different breeds

    This year I decided to try a two queen hive. One queen is Italian and the other is Carniolan.

    They started of as two separate Nucs, which I merged in a long (double width) hive using a vertical queen excluder. To merge I simply placed a frame of foundation on each side of the vertical excluder, then each colony on either side, with entrances at either end (top entrances).

    Bees don't mind having more than one queen, you just need to keep the queens from getting to each other.

    So they were both 4 frames each at the start of Winter (May). I had seen on the forums that a hive will often dispose of one of the queens coming into spring. I believe this is due to one queen starting to lay later than the other, producing less queen pheromones. So to avoid this I replace the vertical excluder with a plywood partition. Michael Palmer style I made it into a double Nuc (also called a divided deep). Placing the brood nest of each (only 1 or 2 frames by this stage) hard up against each side of the partition. Then fed for a few weeks to make sure they had enough stores.

    In early spring (August) when the plum trees were in blossom I checked and found they both had at least 3 frames of brood. The Carniolans were still on 4 frames but the Italians had drawn out a couple of frames ( I assume with the feeding), so had 6 frames.

    My theory is to merge again when each side has at least 3 frames of brood. This is so that the queens are both producing enough queen pheromone. They both had this amount, so I replaced the partition with the queen excluder. Again had a frame of foundation on each side of the excluder, to allow for the merge.

    The population has grown fast and I have seen both queens several times since.

    Having the different breeds also seems to get the best of both breeds. Where one is lacking, the other makes up for it. For example, my Italians are very gentle but don't deal with pests very well. The Carniolan are also very gentle but do deal with pests well. The double hive is doing much better than when the Italians were on their own. So a hygienic queen and a good honey producing (breed) queen could work well.

    Of course they also have a higher population with the two queens. Although I still haven't used any smoke to work on this hive. I just have a cloud of bees hanging around if I remove one of the supers, because of the top entrances.

    Checked today and they have now drawn at least 24 foundationless deep frames (only two of those could have been from feeding). I have also taken out two 3 frame splits. So they have gone from 8 frames at the start of winter (May) to a total (including the splits) of around 32 frames to now (November) and its only half way through the swarm season! On that note, no signs of wanting to swarm. I have been opening the broodnest with this hive.

    So having two queens, and different breeds of queens is an option.

    Was there a reason for having the entrances on the ends, instead of on the side, more or less adjacent to each other? I am very interested in this idea, in part because I have a long hive I built last winter and then did not use. It was built from planks salvaged from an old stock corral, and wound up being about as heavy as a coffin. A bit of work on it and I could put it to use with what seems to me would be an interesting project.

    The top entrances are in the front of the two roofs. I have them closed down to 1/4 each during winter and half the width of each roof for the rest if the year.

    Having the two entrances allows air movement through the hive without having a large number of bees fanning. This is because they only need bees fanning at one entrance, pulling the air out and so it gets drawn in from the other entrance.

    When I super, I use 10 frame or 2x4 frame boxes (half 10 frame boxes). This creates a "U" shape for the air flow.

    I do also have the ability to open up the ends on the base. This is mainly to be able to clean out the base. They could also be used as entrances if I wanted to.

    Interesting Matt. One thought I have...are you seeing an equal mixing of bees? Yellow and dark bees in both ends of your long hive, in nearly equal numbers, or does each end contain mostly bees from its own queen?

    They were acting just like separate colonies for about the first month or so after the partition was removed, but gradually mixed. (There was usually more bees at the Italian entrance). The mixing has been the most noticeable after the supers were added.

    I'm now seeing that both entrances have an equal number of bees nearly all day. If one entrance is too busy, bees will run over to the other entrance.

    I had a look a few times today to compare the ratios at each entrance. Before going into the numbers I should mention that the Italian side has a larger brood nest. Something like 2 or 3 frames more the the Carniolan brood nest.

    So the entrance on the Carniolan side ranged from 1/2 Italian and 1/2 Carniolan up to 2/3 Italian and 1/3 Carniolan.

    The entrance on the Italian side ranged from 2/3 Italian and 1/3 Carniolan up to 3/4 Italian and 1/4 Carniolan.

    I had a look in the brood nest on the Italian side the other day, but wasn't looking at the ratios. At a guess I would say it was more than 2/3, probably more like 3/4 Italian.

    I'm thinking the ratio is always going to be more than 50:50 as you have bees from the one queen emerging on that side and possibly not going far from the frame they emerged from while they are in the nursing stage. So would expect the ratio to be more around 2/3 to 1/3, with the bias on the queen's breed if both brood nests were the same size.

    This is an excellent post. You must be having fun with this hive. Thanks Matt.

    I would be interested in hearing what happens if and when one of the colonies supercedes their queen.

    Very interesting. Thanks for writing this up.

    How is the rest of the hive configured? You say a double width hive, does that mean 20 frames horizontal? Much much space is given for brood? I guess you must be using queen excluders above the brood too, right? Do you have any pictures of this hive?

    I too, would very much like to see any photos you could share. I'm not sure I clearly understand your supering method. Thanks again for this thread.

    The hive is horizontal, 20 frames wide, with a vertical queen excluder in the centre. With top entrances, in the front of each roof, which come down the front of the hive a bit

    Here's a picture of it when I first made it:


    The supers from left to right are, 1/2 width 10 frame, 10 frame, then another 1/2 width 10 frame. The half width supers only fit 4 frames comfortably. I am also using these size boxes as Nucs. A queen excluder is under the 10 frame super.

    The good thing about the 1/2 width supers on each side is that it allows easy access to each broodnest without having to take the whole hive apart.

    For more photos see my website (which I haven't updated for quite a while):

    I've experimented a lot with 2 queening. I've tried side by side, one queen over the other, and the "tower" system.

    But without much success. I would liken the situation to having two magnets next to each other with the "N" pole facing each other. Sooner or later one magnet flips and when it does, the bees move to the queen they favor and abandon the other.

    For example the tower system is two side by side hives, two brood chambers each, topped with excluders, and then a single stack of supers centered. Only the field bees mix in the supers. When the bees moved up into the supers, they avoided the center frames. When have you ever seen that? They would go up two or three supers and hug their side, doing everything they could to avoid contact with the bees from the other cluster. I suspect that in your situation you have something similar. Two hives that will do everything they can to avoid each other.

    In running 2 queens you are basically trying to produce a situation that is not natural for the hive. The only time the hive has two queens is in a supersedure and then only for a few weeks.

    However, I have had great success in honey production by combining two queens. If you takes two weak hives and combine them just before the honeyflow, the combined hive will produce more honey than a single strong hive.

    So, I often run two hives in a stack in the spring. Two boxes over two boxes. Entirely separate hives. I do this with my midiocre hives.

    In our area, the initial honeyflow is overwhelming. The key is to time the combine to be just prior to the honeyflow. In our area, the marker is the locust bloom. Almost always the main flow starts two weeks after the locust bloom fades. So, in the week after the locust bloom, I do a newspaper combine. Timing is everything.

    Not sure this would be successful in other areas where there is not the huge initial flow.

    Checked today and found lots of brood, of all ages! The Carniolan side's brood nest has been enlarged significantly. (I only checked the brood nests on both the sides.) The Italian brood nest is still the same size.

    The Carinolan brood nest now appears to fill the bottom box and the queen has moved up into the half width super. So if the nest is still to the middle, that would be about 12 frames of brood (It was about 6 or 7 last time after taking a couple of splits). The Italian brood nest would be still about 8 frames.

    A couple of random frames seem dedicated to pollen, so have up to 50% pollen. Rest of brood frames around 70% brood with mainly nectar around the edges. Saw a few queen cups (or should I say goblets) on each side of the hive but they were all empty. I removed them.

    The Carinolan side has a denser population of bees and has drawn out more comb. I think a lot of these bees are nurse bees. Probably because of the larger brood nest.

    Population mix still looks like the preference to queen's side is about 2/3 (at a guess). Good mix in the supers.

    The main flow has just started. So we'll see what happens now!


    Here's a picture of the hive with the supers on. (The thing on top is half a pallet.)

    I haven't seen any evidence of them trying to avoid each other since putting the supers on. How did you do side by side? As this is quite different to one queen over another and the tower system. The brood nests are literally joined beside each other, with only a vertical queen excluder to keep the queens getting to each other. There was brood right up against the excluder on both sides last time I checked.

    I suppose whether it is successful or not depends on your goals. Mine are to:

    1. Get lots of comb built.
    2. Test a theory about bees won't swarm if there is a large amount of open brood.
    3. Get a honey crop.

    If the bees end up favouring one queen over the other, that is not a problem as they will be separated again in late autumn/fall ready for winter.
