I have 6 Guinea hens that I have raised with 6 chickens in a brooder and a small run. They have lived in this area in peace for about 5 weeks. Saturday I moved them to a larger coop with the same run. I did not have the fence/paddock ready yet, ( it is ready now). Yesterday we saw one chicken with blood on her back. The guinea and chickens were viciously attacking the one with the blood on the back. We moved her to the hospital room. This morning I let her out with my free range chickens, ( this chicken was free ranger, until she won the lottery to live with the guinea). The free range chickens immediately went after this one pecking her back. WHY???? Will this chicken ever be able to live in peace? I will be keeping her in the hospital now for a week or so until she is completely healed. but I am worried about her. Is she just the bottom of the pecking order?
