I just finished building my coop. It is appropriately sized for 4-5 birds, and I have three chicks in a brooder box right now. The chicks are 4-5 weeks away from being able to stay in the coop. A couple days ago I learned that the wild bird rehabilitation center behind my house has been flooded with people dumping "pet" birds on them, and they're looking to get rid of chickens. I checked it out, and they've got all roosters save for a single silver wyandotte hen. I *think* the way to go here is to pick up the hen, let her live in the coop all by herself for a month, then introduce the three chicks. My thinking is that the month of solitary will a) let me see if the bird is sick and b) help to balance things during the introduction. I figure one lone bird vs. three smaller birds will be more evenly matched if the lone bird already owns the territory. Is it ok to make a chicken live by itself for a month? She's housed with four or five roosters right now, so I think she'd probably appreciate the solitude. Am I on the right track with the introduction? I'm not sure what the best way to deal with the size difference and the numbers difference. It is possible to leave the hen at the center for another month and then let them all into the new coop at once, but I'm wary about the diseases that could be brought in, since the hen lives at a sick bird center. Any advice is appreciated. I've never had chickens before, and I wasn't thinking I'd have to deal with introducing new chickens for a long time.
