I have two Pekin ducks, one Khaki Campbell duck, & 6 ISA brown hens. Everyone got along well until recently. The hens are laying eggs regular though the ducks have yet to lay any eggs. The entire flock is under a year old. Recently, as in 2-3 weeks, the Pekin ducks have been targeting one of the hens. Everyone will play nice when we are in their pen to feed and water them. As soon as we step out the ducks start making a beeline for the one hen. She is terrified. I separated the hen for a couple of days and gave her extra food. Then I separated the duck that seemed to be most responsible for the attacks and reintroduced the hen. I didn’t want her to be separated from the flock for too long. The next day she had feathers removed and damaged in somewhat of a ring near her tail. So, I separated her again and reintroduced the duck. During this process, I started noticing black, tarry stool where the chicken had been perching to escape the ducks. It began to smell pretty bad and my search showed that this could be a sign of internal bleeding. I have checked on the hen today and her feathers are making a substantial regrowth. This has me thinking she is on the mend, even if the ducks hurt her. Soooo…. Now I could use help trying to navigate this social upset with my flock. Any tips for reintroducing the hen so she won’t be attacked? Do you think I need to keep her separated permanently? Does this happen when ducks get ready to lay? I saw the Pekins look up at the hen while she nervously perched on the coop and they patrol it waiting for her to jump down to eat or feed. The ducks seem to be doing fine with the rest of the flock. Also, the separated hen is having normal feces in her confined personal quarters. The separated hen is also laying. TIA!
