I'm fairly new to raising chickens. I have been posting for awhile now since I acquired my one day old chicks last May. I have posted that a few months ago they started eating each other's feathers. I have 11. The brown ones, four, are the worst as their necks are almost bare and their backs are bare. All their rear ends are bare. It was suggested on this thread that I try pinless peepers after my other attempts failed. i.e. fermented food, treats, red light bulb instead of white, radio on for music in the coop (don't laugh). I am having a terrible time getting the peepers on !! Does anyone else have this problem? My husband and I tried to do this for the first time this morning. I even had them warming in hot water so they would be more pliable. I have the correct pliers too - snap ring pliers. But we could not align the pegs with their nostrils. The tool was in the way and we couldn't see properly. There must be a knack to this. We hurt one poor chicken too because the peg pierced the membrane BESIDE her nostril and it was bleeding and she was wincing. I immediately released the peeper once I realized what was happening. Oh dear. There has to be an easier way. Finally my husband was able to do it without the pliers - by getting right in front and on top of their head so you can see both nostrils at once but even then, it's difficult. Two have flown off (peepers that is) and two have remained on. But we have 7 more to go. We gave up after this attempt and will try again - doing one at a time. It's too stressful.
