Haven't been on for a while, kept losing my password and finally reset it. I have 20 barred rocks; I love them. They are great layers and started off laying normal sized eggs, hardly got any pullet eggs from them at all. They are great with us but not other birds I also had a flock or RIR's but my barreds wouldn't allow us to add them into the flock. We tried adding one from each flock at a time into a new coop that hadn't been either groups territory. The mean girls go after any other hens and are very territorial. Two of them got one of the RIRs in the corner and just beat the poor little soul badly, pecking a huge hole in the back of her head that was too severe an injury. We had to put her down. I'd like to get some more hens but wonder if there is a way to get them to allow others to join their group. Anyone out there have some experience with Barred Rock Mean Girls?
