Hopefully, with the BluKote, they will have a hard time finding an injury. I'd try putting her back, because they always seem to prefer being with a flock. She will likely have to return at the bottom of the pecking order after 3 days out. You'll just have to see how it goes. Sometimes you can put BluKote on a really minor wound to cover the scab or tissue and never have to remove them. I've done this with a small toe wound, as soon as it quit bleeding, for example.
