of my bathtub, that is! These are my first chicks and I really had no idea they'd grow soooo fast! DH is building coop as fast as he can and it should be ready this week but nights here in VA are still chilly. They are 5 weeks old, have enjoyed romping in mobile cage during daytime, seem healthy & happy. If I move them to coop will they snuggle up & keep each other warm? Or should I delay transition till weather warms up more? In the bathroom, they really generate alot of heat -- pretty surprised how fast they feathered out. But the reason I want them in the coop is b/c I cannot fit a waterer or feeder in the bathtub that'll last them all day while we're at work w/o crowding them really horribly. It's really standing room only. So I'm worried about dehydration during daytime. I really don't want to haul chicks from coop to house every evening ..... but I guess if I have to. At what age/stage can they handle 40 degree nights by themselves? Oh -- there are 26 of them, all girls. At least I think they are!
