I have a cuckoo maran and a wellsummer that have been pecked and I've been using this and sometimes in conjunction with neosporin to keep the MEANIE chickens away from them. They are missing back and mostly all their tail feathers Does anyone know if the best way to deal with this, besides separating them is to put this on daily, or is every other day enough? How long does it need to be put on? Do the Meanie chickens "learn" not to peck? It can be 2-4 weeks for feathers to grow back in my experience, so I'm wondering if I need to put it on for that long?
