Mine spend all day everyday in the run. I have the greenhouse panels on the east, west, and north sides. The south is open except for the hardware clothe. Except on days when the wind is from the south, then I add half panels up. I wonder if when the sun ever comes out, if it will be warmer in there than in the henhouse. or maybe it already is. Basically they only go in the henhouse to sleep and lay eggs. I'm starting to worry that they will just sit out there and get frostbite instead of going in the henhouse?
Hope not. I'm with you jailerjoe, this frostbite worry is terrible. I've got two that have already had frostbit combs, hope they don't get anymore. I do put bag balm on them on the cold nights like tonight, as well, we'll see. My gold comet just has the little points sticking up, 2 got frostbit, but my Buff orpington has a huge comb, alot of frostbite, but it turned black and fell off.

My EE's and SLW seem fine, no combs to speak of.
I took out the high roost so they are not roosting in the cross ventilation now (my bad)

So hopefully they don't get it again. I get up for work at 4. My husband opens the door for them at 7:30 before he goes to work, it is suppose to still be -11 at that time. I hope they are ok. I wish I was going to be home to keep them inside a little longer tomorrow, just until it warmed up to at least the neg single digits.
