We have 2 breeds of chickens. Bantams (June will be a year that we have had them from babies) 1Rooster and 3hens. And we also have 6 Buff Orpington's. They are 20.5 weeks..we just got one of their firsts eggs the other day! We have a pretty big coop and run attached to it. We currently still have the chickens separated..buffs are in a huge pen we built in the garage and the bantams are outside..when ever we get the chance we let them free range together (not much lately bc of all the snow) the bantam hens are very mean the the buffs. I feel like it's never going to happen that we can put them in the big pen all together..while free ranging if the buffs get to close to the bantams the bantam hens go after the buffs. Not so much the rooster though. I'm at a loss on what to do about it..we have put them all in the pen and my husband and myself have even sat in there with them and the bantams will still attack the buffs...they are all super friendly except the 3 bantam hens..even the rooster is very friendly. He rubs on your leg like a cat for you to pet him or pick him up but the little hens will run away they never want to be around people..if I can't work something out I may have to get rid of them . Has anyone else had a problem joining flocks?
