Bad mother woes

I'm a bad bee mother. I hang my head in shame. I'm getting burr comb and dead bees on Sunday, I can feel it. I went out to check on my girls (and Joel's) today now that the rain has subsided. When I say "check," I mean just pretty much look at the front of the hive (to see if they are active; Joel's were, mine not so much) and tip the top cover to see if they need more syrup (Joel's can still has some in it, mine was bone dry). So...it was cold, it was rainy, the bees were stuck inside, and I didn't even give them any nutrition to tide them over. I feel terrible. I topped off the jar and replaced it, I'll go out in a little as it warms and suns up to see if they get moving again.
