I hope I'm posting this in the correct forum. If not, I apologize. I am in desperate need of advice. We acquired a chicken coop in April and decided to start raising chickens. We got 4 Buff Orpingtons, 4 Americaunas, and 4 Orpingtons (black and white) on April 4th. Everything was going fine with them until 10 days ago. We came home two Sundays ago and saw that one of the Americaunas had been pecked pretty badly and was left with just one tail feather. We separated her immediately. I went into town and got a product that our local co-op recommended to put on her bloody quills. By the time I got home, another of the Americaunas was in the same condition. We set up a temporary pen for them for during the day and a temporary coop for them in the garage for the evening. Two days later, I had to add a third Americauna to the recovery pen/coop. On Saturday night, once the other 9 chickens (I think one is a rooster) went in to their coop to roost for the evening, I snuck the three Americaunas back in. The next morning, I separated the last Americauna (that one had been doing the pecking) so that the other three would be OK back in the main run. Two days later, I noticed that the one Americauna had been pecked very badly again. One of the black and white chickens (Orpington??) had turned into a pecker as well. I put the one Americauna back in with the main flock and removed the three that had originally been pecked and put them back in the temporary run/coop. I spoke to my husband last night and we have come to the conclusion that we need to build a bigger coop for the chickens. The one that we got is 8' x 4' and I have come to the conclusion that it's not set up very well and it's probably on the smaller side. There are three perches for the chickens to roost on at night. Each one is 4' long - they are centered in the coop and run from the front to the back. There is one that is at a higher height than the other two. There isn't a poop board underneath (no wonder I was having to clean out the coop every 2 to 3 days) and the chickens all tend to try to get up on the highest perch. What suggestions do you have for a chicken coop? How large should it be for 12 chickens? Any ideas on what we can do to curb the chickens that are pecking the others? I went out today and now one of the Buff Orpingtons has bloody quills. I tried separating the three chickens that I saw pecking her, but they're hopping the divider. We were really excited with the idea of raising chickens and having fresh eggs in the morning, but I am feeling completely overwhelmed. I am at a complete loss with what to do. We have been told that we shouldn't have mixed breeds of chickens - our local co-op didn't tell us that when we were buying them. My husband has made the comment tonight about getting rid of all the chickens, but I don't have the heart to do that. I consider them as much a part of our family as I do our cat. Any advice for coop design, what should be included in the coop, why they may be misbehaving, ..... would be greatly appreciated. I was so excited about this initially, but I'm not sure where to go from here. Thank you!
