I've been keeping mine in a 75 gallon aquarium in the basement because the brower brooder in the garage didn't keep the temps stable enough in the bitter cold temps we have been having. Now that they are 4-5 weeks old I just moved them into it again and I'm watching to see how they do. I can't handle the smell in the basement anymore. It's not bad when they are first hatched but after 3-4 weeks it gets unbearable. The ones I moved to the heated Brower brooder in the garage have a lot of feathers and the temps say 90-94 degrees but they are all sitting around huddled up like they are cold. Has anyone had experience with this? Are they going to be ok or do I need to put them back in the basement for a while?
