Re: Pollen stores for winter; necessary?
The bees also use them for raising the big fat winter bees.
Though they will not use much but does provide feeding to fatten up the
winter bees. This will help them being fat going into winter to keep the
cluster warm burning through their fat reserves. Just leave it anything they
don't use up for winter will be fine for the Spring broods. And don't worry about
the extra space inside as they all cluster together in the cold anyways. There will always
be some extra space unless you packed them inside full of bee like my deep nuc hive double queen
set up going into winter.
Don't mix foreign bees into a virgin hive. She might get balled 100% of the time! When will you ever learn, huh?
