Hello, I'm new here. We got a dozen chicks from a local farmer and I asked him a bunch of questions but don't want to keep calling with every little thing. Anyway, my babies are only 3 weeks old, but was wondering when can they go outside? We have them in our basement with heat lamps on and florescent light during day and turn off the florescent at night (to mimic daylight). When they do go out there is a chicken house and a very large coop. Do we still need to keep a light out there in the house? Thanks for your advice! Here are a few of my babies.
