Last night my DS and I put the pinless peepers from eggcartons.com on the chickens. I have 8 chickens and with the exception of 2 chickens, they all have bare bottoms! And the majority also have bare backs, and I have tried everything else associated with feather picking causes and this is the last resort before I re-home these chickens to a place they can free range again. My feather picking started over the winter this year when we had heavy snow/winds and they were in the coop/run for a long stretch of time, when they were used to free ranging. This spring then, we started the garden and the farmers started the fields so I have kept them in their run and it's a Very Large run but the feather picking got Alot worse! I rehomed 6 chickens and thought the feather pickers, but it continued, so I rehomed 6 more who I thought were the culprits. Things were better for a few weeks and then it started again. They have no mites/lice, protein is good, they have Plenty of space, they are just Bored! Soo we're trying these "peepers"! No instructions come with them, so I just went by pictures on BYC. We did not buy the tool that goes with it, you can easily stretch them out to put on, it did take 2 people though, because 1 could not stretch them and hold the chicken at the same time. I used a little stool, and I sat and held the chicken between my legs and held it's head good while my DS clamped them on. Then we let the chicken go, and the 1st try we thought we had them on but she brought her leg up and itched and the peepers flew off! But from then on, we were good! The other chickens did peck at her peepers, but once everyone had them on, that stopped. I will keep you updated on the progress, I'm hoping this solves the problem and if not I will rehome my chickens to the same people who took the rest of my flock.
