I have four hens, all the same age that have done very well together for about a year but recently my Wyandotte has started pecking my Ameraucana (who is much smaller than the other three). The Ameraucana is almost bald from all the pecking. I separated the Wyandotte in a small dog crate inside the run ad have only let them all be together when they are free ranging in the yard. I was hoping the bring the Wyandotte down a peg or two to stop the bullying but now one of my Orpingtons is also pecking the Ameraucana. What should I do? I am in the process of building a small add-on to the coop/run for new birds that are coming in a few weeks but it is not done yet. Should I move the two "peckers" to the new space or should I move the Ameraucana. I am afraid if I separate her that she will just be pecked again when I have to put her back in when the little guys arrive. Any bright ideas? Thanks!
