I have a mixed flock of about 20 birds, One mature resident Rooster, 2 Juvenile roosters, and hens from Japanese up to a Jersey Giant! We have a Hawk population that so far has only claimed one polish hen this spring. But I worry. I have heard conflicting information regarding Guinea Hens. One person told me they will kill chickens....? Others tell me they are territorial and attack strangers...? I have a Garden Center and people come with their children to feed and pet the birds, I can not have anything aggresive.... I have Cats and Dogs that work together to keep the Chickens safe (strange I know) my cats hunt the weasels, and the dogs the coyote and fox and fishers that live nearby. Will Guineas bother these furry members of the flock? What is the truth about Guinea Hens?
