Will they be ok? I'm in Ma. Its going to be 47-50 degrees tonight. I have them in a 3x6 coop that Is filled with almost a foot of shavings. The are fully feathed. Lately they have been moving away from the warmer areas of the brooder and sometimes panting if they all group up and snuggle. Water and food is with them outside in the coop. There are 5 of them in the baby coop together.
