I have a cochin hen that went broody with no egg(she goes broody all the time lol). Anyways I thought she was finally coming out of it, a few days later she was loosing all her feathers, wings and feet. Pretty sure she wasn't pulling them out. And she was having a hard time walking. So I brought her inside. She wasn't as happy as she usually is, didn't really want to walk even when I tempted her with cheese. She is getting rooster booster and feather fixer, and maybe twice a week getting some crushed high quality dog food (like 3 pieces smaller than a dime) made with salmon. She seems to be doing better and her feathers are really coming through on her feet now. She still seem to be a bit sore on her feet though. She is starting to come after her cheese now. I guess the main question is if a cochin goes through a bad molt can it mess up their balance? So sorry for the long post, just trying to give all the details.
