I have a Barred Rock hen who is 18 weeks old. My rooster is young and agressive with my hens... and this hen has a hard raised spot on the back of her neck. I know it is from the rooster. Some feathers sticking up and a hard spot that is slightly smaller than a marble. It does not appear to be cut or open. I took Blue Kote out and was going to spray the spot but didn't really know what to spray. I just want to make sure the rooster doesn't hurt her. Should I try to separate them? I don't really have anywhere to put chickens other than my coop. The girls just don't appreciate his attentions yet...
