I have 9 hens roughly 5 months old (5 Brahmas, 3 Delawares and 1 cochin) everyone had a pretty good molt and seem to have recovered well however I have one brahma who still hasn't grown back her tail feathers and I notice a little blood on one feather. It looks like it is slowly starting to recover back there. I don't see any of the other girls majorly picking on her, only time I ever see my girls get huffy is when I am handing out treats. I purchased some blu-kote but I get mixed vibes on if I should use it on her tail area. Would this help her?
