Hi All, Appreciate tips/insight here. A bit of background: I currently have three sub-adult birds. Two Jersey Giants and One Ameraucana Rooster. Both of the hens aren't super-hand tame but also aren't mean. The boy is about six-seven months old, crowing, and is very sweet to the girls. He hasn't tried breeding with them yet, just shows them treats etc. Before we talk about the hen ratio, I also have recently rescued (for lack of a better word) 7 three to four month old "chicks." I am not sure if these newer birds are hens/roos yet but at this point guess I have at least two roos out of the bunch. In addition to these birds, I also have 6 nearly 2 month old black Australorps. All of these birds are kept separately at this time, and were adequately quarantined (more than a month). I lost one bird during that timeframe and realized they had coccidia; after treating, the birds are healthier, albeit still trying to regrow feathers from how they were kept in their prior "home." When I received the 8 rescue birds (now 7), almost all of them had little to no feathers and it was obvious they were kept in very close quarters (looks as though they've picked each other to no end). Very unlike my pristine black Australorps. I am having another coop built for the younger generation to have them reside next to the older birds (see but not touch.) The little ones currently live in my garage - can't wait to get them moved out of the brooder in there... What I'm hoping to hear from you on: 1) Is it pretty typical roo behavior to literally attack newcomers? I've never seen this behavior with my hens as this is my first roo. He seemed to attack everyone, pullet or possible roo. I'm used to the usual scuffles and all that with new birds, but haven't seen an outright attack. He was pushing them against the fence, jumping on them, just generalized attacking. 2) Would putting the roo in the coop by himself (the new one I am constructing next week) be better? I have another large coop big enough to accommodate everyone...the hens are doing the typical pecking order stuff, but nothing major. More of a curiosity of "OH LOOK WHO IS NEW!" Thanks guys and gals!
