I have 6 baby chicks that will be five weeks old on Saturday. They are pretty feathered out and they are getting way too big for their brooder. When can they go stay in their coop? I live in Texas so it is not terribly cold. Today the high was 80 but the next couple of nights they are expecting lows to be around 30. The hen house itself is enclosed with cedar wood and that is where they would be staying at night. If it is too cold to move them outside right now can I move them to my garage? They are smelly little things and I change their shavings everyday. I took the brooder lamp off of them about two weeks ago. Thanks!
