I have 5 six-month-old chickens (4 hens, one rooster). We are going to get 5 or 6 more day-old pullets in April, and I want to prepare everything for them before they come, so we aren't in a hurry. (They grow so fast!) We will start the chicks out in the basic cardboard box brooder. How long can they stay there? Next, I was wondering if we have to build another tiny, cheap, easy house for them when they get to old for the box, but they are too young for the coop. Do you think this is necessary? How old should they be when they go out there? How should I make this temporary house, if at all? How old should they be when we put them in with the big chickens? How should we do this? Our coop is about 10 by 5, so we don't have tons of room (though we do have a run). Should they be isolated with chicken wire or something? I know it's going to be tricky, so I need some help!!!
