My 2yo Jersey Giant had accepted the 5month old Cochin and Welsummer has her new flock until recently. The Cochin started laying eggs last week and Roberta, the Jersey, has started pecking at her. I noticed it first a couple of days ago when I was interacting with Charlotte, the Cochin, and Roberta pecked at both of us. I thought it was strange and that it maybe had something to do with me. Today. however, Roberta ripped feathers out and actually wounded the back of Charlotte's neck while Charlotte was laying her egg. I am trying to figure out, first how to treat Charlotte's wound and second how do I stop Roberta from being territorial either over me or the nesting boxes (there are three boxes). I have cleaned out the nesting boxes and placed eggs in each box in an effort to show them that all of the boxes can be used for laying, but Roberta keeps shoving the eggs out of the boxes (they are her eggs). The birds free range in the yard all day. The coop is 4' x 4'and includes the nesting boxes and roosting bar. So there is plenty of room for the three of them. Any advice will be appreciated. Thanks.
