About three weeks ago one of my hens (Mocha) starting attacking another hen (Mildred). Both are Khaki Campbells, purchased and raised together. Never had a problem before. I wondered if it was breeding time/hormones, attacking a weaker (sickly) duck, or just that Mildred is the drakes "favorite" hen and drakes have never wanted much to do with Mocha. The saga continues. Mocha is now attacking my new young drakes - attacking throats. In the duck house at night, she squawks all night long. They are separated in the duck house, and at this point have no where else to house her, unless I bring her in the house in a carrier. Just curious as to whether anyone else has had a similar problem. She is quite aggressive, seemingly desperate for the drakes attention. Was hopeful that it would lessen by the end of August/early Sept when the breeding frenzy got a little less, but so far that's not happening. She seems heathy otherwise, eating well, feathers look good, but she's seemingly gone nuts!
