Hi, this is my first post to the forum, but I have been utilizing all of the wonderful information here for months! lol I have 12 hens (a few are pullets still) and one Buckeye roo. The roo is about a year old or maybe a little younger. The hens are all under a year. The roo seems to have one favored hen and she is barebacked (going to look into ordering a saddle for her). They are in a coop at night, and free-range in a large yard from about 7am until 8pm. We live in Tucson, AZ and it has been very hot, but the chicken yard has trees and an awning for shade and they have plenty of water available. Anyway, this morning I noticed my roo is losing feathers on his back at the base of his tail. It looks very similar to the barebacked hen. I couldn't find any other posts on this type of feather loss. I don't see any missing feathers around his bum, chest or neck, just this area on his back. I will be checking for mites tonight and putting down DTE just as a precaution (or to hopefully take care of the mites should I find any). Is there anything else I need to be doing maintenance wise in my coop? Thanks so much for any input and thoughts.
