Flo, my two-year old EE is a confirmed feather picker. She's been wearing pinless peepers for the past eighteen months, having them removed from time to time to see if she had reformed. I had been feeding her a supplement and wished to see if it had made any difference in her feather craving. It didn't, since she began shaving feathers as soon as the peepers were taken off. So I installed the bumper bit device I had gotten from Britain since they aren't sold in the USA. It's a bit that fits in between her upper and lower beak to prevent her closing her beak all the way. Has anyone used these? Can you reassure me Flo will still be able to eat and drink? I feel as miserable as she is feeling , adjusting to this foreign object stuck in her mouth. And all the rest of the flock has ganged up on her for appearing different. I'm feeling guilty for doing this to her. She really is one of my most lovable lap hens.
