My Rooster (A Rhode Island Red) keeps attacking one of my hens. I have no idea why he keeps attacking it my husband and I believe that he thinks that it is a rooster but it is definitely not we got it last year as a bitty at chick days at tractor supply, the bitty was in the same crate as the americaunas but is definitely not an americauna, the hen produces a light brown egg as opposed to a colored egg. Any suggestions as to why the rooster is attacking the hen. It is very frustrating having to quarantine a chicken!!!!!!
