I posted about my pecking issues. My two major peckers starting off are 2 Americauna dark color hens 11 wks old, followed by rir hen. The Delaware and marans join in when it gets going. I have not noted the buff orpingtons or barred rocks doing this. I received my peepers and put them on the major offenders. The one they messed up was the smallest Americauna (black) then the other Americauna's grey, tan and black and white. They did not bother all the slightly smaller ones (by 2 weeks) buff orps, delaware, cuckoo marans or barred rocks. Is it a breed issue? Is it because the Ameracuanas are the oldest/biggest? Is it Ameracauna? Is it because I have a big mix? I have all ready figured the baby polish chicks & appenzellers (mohawk crest) are probably have to be kept seperate instead of mixing in when they get older. Can you keep polish with silkies and appenzellers? Or how about with buff orpingtons? Or will buffs gang up on a different breed? A small peck here and there is one thing but pecking till bloody then having to seperate is a bit much. I have the two pecked Amer. in a dog cage together-they don't bother each other (yet). Is this ok? I'm trying to decide if I sh/give up on certain breeds. I wanted a lot of different chickens not all the same. ADVICE or OPINIONS PLEASE !!!!!!!!!!!!!!!
