This is pretty bad but somehow one of my chickens fluttered to closely to the pull string on the light in their coop, and it wrapped around the wing. We found the chicken hanging by its wing probably a few hours after it happened, got it down and fixed the string so it wouldn't happen again. However, the chicken is dragging its wing now. I have been reading about wrapping gauze around the chicken to hold the wing in place, but everything I've read says it has to be separated from the others too. I don't really have an easy place to do this - is it required to separate it?
