Well I am puzzled reason being is because today I was out feeding my hens, as I was feeding they always follow right behind me but not this time. One of my Americaunas were jumping and grabbing the back of one of my other Americaunas neck feathers! They just kept chasing each other around and around the run..... So what should I do? Just leave them be? Why is she (or he still not sure) doing this? I think they are about 2 months old... Thanks for the advice and help!
