>I had 3 hives that I started in the Spring of 03 and they were going great guns, but, for some reason they bailed out about this time last year.
Mites are a likely suspect. Varroa or Tracheal, but I'd tend to suspect Varroa, just because it's more common. You need to decide what you will do to handle them. There are lots of alternatives available and discussed regularly here.
>Why mediums for brood? Seems to be asking for swarm probs if you don't pay attention and add more in a timely manner.
And I start mine in a five frame medium nuc. But then, as I said, it's pretty cold at night in April and they need to be warm. In a month I move them to an eight frame box and then a ten frame and then add boxes. But in the end they end up with as many boxes as they want for a brood chamber since I don't use an excluder. Why would they swarm?
Why mediums? Deep full of honey = 90 pounds. Medium full of honey = 60 pounds. Eight frame medium full of honey = 48 pounds.
>I start everything (splits, nucs, pkgs) in a deep as brood chamber, add one medium as bee stores that is NEVER robbed, and then add mediums for harvesting.
Why would you want two different sized frames in the brood chamber? Isn't it a pain when you want to rearrange things?
>Less work, good production, less swarm probs.
Than what?
>I'd have a follow-up on starting in mediums. I have a truckload of mediums that were used as honey supers. They're full of drawn comb that's in decent shape. Is this kind of comb ok for use in starting from packages or nucs, or would I be better off installing just foundation and saving the drawn for supers?
Well, it depends.
If you want small cell, then I'd put them on that from the start. If not, drawn comb is always an advantage.
