"My question for you River: if the bees wont' move down in the winter to get food, why is the bottom brood box usually completely empty in the spring time (at least mine seem to be). I don't open my bees up till it gets fairly warm, so it could well be that the bottom deep doesn't get cleaned out till spring. I always thought that the cluster forms at the bottom of the hive and gradually moves up during the winter.
We don't have wax moth or SHB up here, that may well affect management styles too."
pete, a great question. the cluster does form at the bottom, because the bees have 'forced' the queen down storing for winter months in the top deep. the bottom box empties typically well before we realize it is. the bees use these resources, sometimes, not always, before they move up. also throw in your breed of bee, and how conservative or not they are. sometimes we will find honey remaining in outer frames and the colony starved in the top deep, totally empty of any honey. or we thought that bottom deep had stores in it, and it didn't to begin with. sometimes we think that bottom deep has stores in it, when it does not. i always check before cold weather sets in to see that there are frames of stores in that bottom deep. not sure how to explain this, but i can gauge when a hive is top heavy as cold weather progresses. the bees do not move down, or will not go for those resources, if any, in the bottom deep, and sometimes in very cold weather will not move from side to side in the top deep. in warm spring months, i often find honey in the outer frames in the bottom deep.
i hope i answered your question?
my management practice in general is not to place or leave any box on a hive that the bees cannot protect or defend. ants, waxmoth, mice, or other pests/critters. and bees tend to chew wax from unused drawn comb to repurpose elsewhere. in my HO it makes more sense to me to remove jen's deep in the near future that contains feed in it and to place it on top at a time when it is most needed, be it now or later. in winter months, we can't exactly reverse our hives to put the feed on top for the bees to utilize, because we know the bees move upwards.
looking at jen's photos, it would appear the bees have tried to ready the deep frames for the queen to lay in, and it also appears some wax has been chewed? the queen didn't move down, and i highly doubt she will now. if jen had a different configuration, she could have moved the queen down, (same size frames) or reversed.... i don't remember the history of the hive? and maybe jen, you tried this? was this deep on top? and maybe the queen didn't move down to lay because there was a honey cap there?
if jen, you had time in your climate, you might consider placing that deep on top and feed them with a one gallon pail of 2:1 til the bees packed away some extra feed in that top deep. i don't know if you have time for this. they will need time to 'cure' this before your winter sets in. i am thinking you might not? another option would be to consider placing a shim on for winter feed, or candy/fondant board on. or just pinch that queen and combine?
i think apis at one time suggested that he thought you could overwinter your bees with a deep and a super with no problem jen? pete suggested 60 pounds for your area, looking up your location, pete may be right on about this.
also, consider your bee genetics, italians can really blow through stores.
hope this helps?
