Hi I am new to chickens. We just bought 10 acres and bought 12 month old barred rocks from the feed store. They were over crowed and some were pecked. We put them in a large brooder with tons more space. They have all been pecking each other and we can't get them to stop. Some to the point of bleeding. We tried the vicks and it helps for a while. The weather is not warm enough yet to get them outside. We are feeding chick starter. They appear to be eating the feathers as none are laying about. I would separate but all 12 of them are pecking. Now they are even pecking themselves. We have had them for a week. Any advice would be appreciated. Thank you. I have been reading all the threads on pecking but most have to do with older hens.
