This is our 3rd (or is it 4th?) year with hens - We've always had 4-6 hens in the same size coop as we currently have. Right now I have 4 ladies, all about a year old - we got them all over the summer. 2 Javas and 2 Marans. They are pecking the heck out of each other - I don't really see it happening a ton, but they look like crap. Is it these particular breeds (or one of them?) that makes them more prone to this behavior?
