We are excited we just picked up 2 Buff Orpingtons. 2 silver laced Wyandottes and 2 Auracanas. They are two days old. It's June on Long Island, this weekend it will be 80 outside. We have no garage, they are in a brooder in a vacant bed room now. How long before we can put them in their very secure chicken coop? Or put the brooder in the chicken coop? We also wanted to know when they can have lettuce along with their organic chick starter? What's the opinion out there?
