It's that warm at night? They will be completely fine. They don't need heat. Trust me.I was going to just for a night or two because it’s been in like the teens and twenties at night lightly and they are going from a at least 50 or 60 degree possibly warmer basement... that’s cruel to me even if they are technically fully feathered haha
Besides, it’s not really heat, just the brooder heat plate which they probably don’t even fit under anyway and probably won’t even use. But I just thought I’d offer it in case. They’ll probably just decide to roost
But honestly I might just wait until it’s a little bit warmer.
