...At this point I am afraid to pull any more brood from my healthy hive because I don't want to weaken it. Any ideas on anything else I can do?
Also if it doesn't make it what should I do with the frames until I can start another hive? Store them and get a package in the spring? There probably will still be some drone cells and such and there is still a lot of pollen and some honey. Good start ups for nucs? I did have a wax moth infestation so I was thinking I should freeze them. Just didn't figure dead bees in cells would be good.
If I were in your situation I would find myself trying to see if anything could be done to limp the weak hive through, and if you can't, you still have options like you said. Your area is so much different than ours.
Combining this time of year in my area would probably not be successful, but in your area there may be a different outcome if you tried it.
If it dies, hold on to all that comb. Freeze it just as you said in your other post, and then use it to add a package to, or give it to your strong colony and then do a split later. If you can split earlier in the year you might have better luck, but again you'll have to gauge that off of what flows you have in your area (and when). In 2007 my packages that I threw on already-drawn comb went like crazy. If you clear the dead cluster out (if they die) and add to another strong colony, they'd clean out the dead bees very very quickly. You could pull frames of brood up into the additional box to bait them up and you'd probably be very pleased with the results, or at least that's the way it's worked for me. Boomers can be split quite easily and still yield a crop in most cases.
Hope this is helpful.
