Hi! I only have one rooster, it's a long story. Anyways here in Texas the weather is finally getting a little cold!! Tomorrow and tonight is going to be real cold and rainy, he sleeps in the coop by himself but hangs out with my rabbit all day. How can I keep him warm. Will feeding him eggs or scratch grain before bed help? I put shavings in there. Is there anyway that I can keep him warm? Thanks!
