Oh okay. Good to know. I guess I'll just keep them outside unless it's a lot below zero, and even then I'll put them in the coldest room in the house without heat. That will ensure that they don't get too hot while still not being exposed to dangerously low temps.
I'm also curious to know if the chickens like it. Tomorrow is supposed to be extremely cold so I was thinking of bringing my two BOs inside. They are both full grown and I don't want to buy a diaper if they're not going to like it/let me put it on them.
Do fully grown hens mind all of a...
