i live in north alabama the nights right now are running at about 50 to 55 degrees. my girls are around 26 weeks old now. they have been sleeping on top of the chicken house. it is completely closed in top to bottom. i even have a tarp over the top too. my problem is i have been trying to put them inside the house because cold weather is coming on and i want them trained to get inside it. anyway i have been doing this 2 nights. they would rather be on top but i have been persistant. anyway we are going camping to night so that will leave them here to go to sleep by themselves will they be ok at that temp or do i need to come home to put them inside their house?
