Hi- I have two chicks that are about four weeks old. They're nearly fully feathered and are getting big - I'm going to put them out in the coop soon, but probably not for a couple more weeks. That said, when should I switch them over to regular feed? I'm feeding them Manna Pro chick crumbles right now, and the feed that I'm already feeding my fully grown Rhode Island Red outside in the coop is a non-GMO food I bought locally. On another note, I live in Austin, so it's definitely hot here. The chicks being cold is no concern... do you think it'd be a bad idea to put them outside at six weeks, or should I wait the full 60 days as suggested in the 101 section on this site?
