Hi everyone I'm new to backyard chickens and I can really use some help about ducks. I bought four ducks in the early spring. Two are khaki Campbells and two are pekins. They were all raised together but as they got older my one pekin would attack the other three. I then separated the pekin and the khaki Campbells. Now it seems that none are getting along. My khaki Campbells are attacking each other and my pekins are attacking each other. They are all males and I could really use some help. I don't know what to do.
