This is a silly question.... I know chickens can handle some pretty low temperatures without problems....but we live in Florida. The coldest it has gotten this year is low 40's. Tomorrow night it is supposed to get down into the 30s and we will have freeze/frost. Our chickens are not used to these types of temperatures..Do we need to do anything to keep them warm? We can give them some scratch before bed to help with body heat..but what else can we do? Their coop is wood with two windows up at the top and another window on the door. We have another chicken who is completely free range, she will not go into the coop and we can not put her in there because she is mean to the others. She sleeps on our front porch and is pretty exposed to the wind and everything...what can we do for her to protect her from the wind and freezing temps? (I know that she should be in a coop at night for her safety please do not lecture me on that...we have tried multiple times, she was a wild chicken when we found her we have tried to put her in a coop before and she will leave and not come back for days..she is safest on our porch or in our tree, rather then out in the woods..) Any information would be great! And I know that these are not usually temperatures that would cause someone up north to worry about, but our chickens are used to weather in the 70's not 30. TIA!!
