I live in Portland, Oregon and have three 6 week old chicks: a Barred Rock, An Ameraucana and a Buff Orpington. I need some advice on when I can transfer them outside to the chicken coop. I know they'd need a heat lamp, which they are already basking under, but would dearly love to get them out of my bathroom. Any suggestions? How-to's. Thanks, as you can see I am very new to the world of back yard chickens.
