9 or 10 frames in the broodchamber?

I would like your opinion as to which is best: the use of 9 or 10 frames in the brood chamber. I have seen a couple of opinions and cannot make my mind up. The 10 frame configuration is closer to what we find in a natural environment.

Whatever you do, keep the frames all pushed tightly together in the center of the box. If you use 9 frames, you will find the outside ones extra fat on the outer side, but will still have more room to take frames out.

If you space them out, you will get a very large amount of bridge comb at the top of the frames and the honey arc will be very fat and uneven, making it very difficult to get the frames out without making a mess. Bees respond to extra space above 3/8" by building comb to close it up, and you will have far too much space between brood areas as they will NOT draw brood comb deeper, it stays the correct depth for raising brood, no more.

I did this my first year, learned quick. My brother tried spacing out nine frames and had a nightmare, lumpy comb that "interlocked" so it was very hard to get frames out without damage to the brood area, drone comb in patches everywhere, etc.

I'm trying narrow frames this year, I think it will produce much better brood comb, less misplaced drone comb, and better wintering. I have a couple nucs ready for swarms, and I'll replace any frames I take out of my existing hives for nucs with narrows until I convert them over.

I cannot see why the extra frame would make a difference to the total area that the queen has to lay in. Studies have shown that a good queen can only use the equivalent of FIVE full brood frames, even though this might be spread out over 8 frames or more.

Surely the difference between 9 and 10 on the brood surfaces means a single layer of bees in the 10 frame and a double layer in the 9. This surely allows the bees in the 10 frame to cover more brood, keep it warm and expand faster in the spring.

However, what happens with ventilation? Is the 9 frame able to cope with keeping the hive cooler in high temperatures than the 10?

What you say that studys show may well be true, but what I have seen is that sometimes I will see brood in 8 or nine frames in a ten frame deep. Sometimes that frame up against the feeder, a drone comb, will be layed both sides. Usually the outer sides of the two wall combs are full of honey, but rarely brood and at times the next frames in will have brood on the inside side of the combs, but not on the outside sides of the second combs in.So, take a comb out and not only are there then, (what 4,000?) fewer cells available, but the environmental buffer afforded by those outside combs full of honey is also lost. I think.

i started with nine, because that's what the first person that helped me told me to do.

i have since switched to 10, and push them tightly together.

i like this better because:

there less propilizing in between the frame's end bars
they are easier to pry apart using the crook of the hive tool
the comb is more even
i roll less bees by 'sliding' the tapered stops on the end bars past each other when putting them back in
i have read the bees preserve heat and cluster better with that spacing

i use nine frames however, in the honey supers, to get the fatter honey frames.

Actually, needing two layers of bees means it takes twice as many bees to cover the same amount of brood, not the reverse. There is also more air movement in the wider space, which means more heat needed to keep the brood warm in cold weather.

In a feral hive, the brood combs tend to be about 1.25" apart, with drone brood and storage combs spaced more like 1.5" on the outside of the brood nest. Varies a bit, obviously, and we are putting frames in the hive and variable spacing isn't really possible for more than a few hives.

Narrow frames (1.25" spacing rather than 1.325") always gives flat comb all the way up to the top of the frame since the honey arch isn't thicker than the brood area, reduces the bees to a single layer and lets them control the airflow a bit better.

A full depth Langstroth frame with 5,4mm cells has about 3,250 cells per comb face. That is about 6,500 cells per frame. If we have a really good queen pumping out about 1,500 eggs/day then it will take her about 4 days to fill the area of a single frame. 21 days for a brood cycle and we can see that the brood area is maximum 5 full frames. The rest is pollen and feed honey, which, when is in the outer frames, acts as a stabilizer against temperature fluctuations.

How about 11 frames per deep
Some small cell beek trim the frames to fit 11, I would but it's alittle hard to trim the frames with bees and brood.
I use 9 frames in the suppers.
I made some medium boxes out of some left over 1/2" OSB I had. The outside measurements are the same as my commercially bought boxes and they fit 11 frames just fine. :lookout:

I was told to use 9 frames in the 10 frame brood box, so I did. Then I put the other frame back in. It took a bit of adjustment, but now the frames are a lot easier to get in and out of the boxes and the bees seem a lot happier with it. I am thinking about possibly shaving down some frames and seeing if I can get 11 frames in my normal/commercially bought boxes.

My brother's bees are very dark, and man to they stick things together! Been known to close the bee escape hole and block off most of the entrance, too.

However, they are tough -- had a very light single deep make it through the winter last year, not that we had much of one, and typically they don't have problems with mites most years.

"German" black bees were popular some years back for this reason, but the amount of propolis them make puts people off them in favor of Italians.

If you want to go with narrow frames, it's best to make them with 7/8" wide top bars. This leaves 3/8" between the bars. Makes them easier to get out (you can get a hive tool between them more easily, or at least I can) and the bees appreciate the extra room. Brood comb with be flush with the bar, too, so will honey storage.

With 1.25" wide frames, 11 fit very nicely with enough room at the sides to pull one back with no problem. Bees seem to fill them out just as well as the wider frames, and the brood combs are wonderfully flat and even.

I can support the large numbers of frames with brood. Our goal is , excluding the two outer pollen frames, 8 frames down, with 5 hung up in a single deep brood chamber. Most frames will be well filled with brood, with a small triangle of honey in the upper corners. Make that Queen Work!!!

When I prepared for bees, I read somewhere that 9 frames/10-frame box have some advantages. If I remember correctly, the main advantage of having 9 frames in the brood-box was a bigger space, which prevents mites to be transferred from one bee to another - instead, mites drop on the screened bottom. I decided to setup my beehive this way since had no personal preference (or biased mentor) at that time. My situation even more complicated because I decided to go foundationless from the very beginning. So, after one full year, I have the following:
- I crush-and-strain honey.
- bees were never treated. Varroa 24h counts on sticky board are stable - 10-20, which considered to be high!
- bees produce perfect parallel comb with very little cross-comb. In September, I gave them the empty super with foundationless "bars". Since September, they filled it up with perfect parallel comb and honey (not capped yet). Another supper is 70% full.
- It is quite difficult to remove frames, but I have none to compare. My understanding is that my bees LOVE propolis! I use propolis for medical needs - win-win situation.
- Honeycomb is 1.5x thicker than usual (I had a few frames with foundation from the past).
- I collected so far approximately 30 kilos of honey, but keep in mind that 1-2 full of honey supers are permanently at bees disposal, they never tested the syrup.
- byproduct of my tiny "bee-business" is wax for candles, propolis for health and honey-wine, the mead. So far, my friends feel that mead is the best part.

Unfortunately, my "experiment" is incomplete because there is nothing to compare and I have only 2 permitted beehives total. Nevertheless, I feel, there are few possible advantages of 9/10 configuration in combination with screened bottom and foundationless:
- I attribute my high varroa counts to the bigger space between frames, so live mites drops and ended up on the sticky board. This way, more mites removed from the beehive leaving less mites on the bees.
- in SoCal ventilation is important - bigger space and screened bottom board looks like good for this.
- foundationless in general, gives bees more flexibility, so they could plan their space accordingly.
- It is my believe that many bees problem are originated from the stress. Less stress - healthier bees. In my situation, it looks like, combination of factors make bees healthier and therefore less prone to diseases and mites. I need many more years to prove this statement.
