I've got 6 little bantams coming next week. A couple ? I'm in So. Cal. So its hot. How old do they have to be to go in the coop outside? In the coop we've got 2 (rooster & hen) white silkies. Will they do ok with the new chicks? You think? How old to start regular chicken feed? For my chicks, I need a box, heat light, waterer and food.... anything else? THANKS!!!!!!!!!!!
