I found two of my quail that had the skin on their necks torn. I have separated them from the other quail. I checked the bobwhite quail and the coturnix quail around their heads for blood splatters that could of got on them if they attacked the other quails but did not find any. I'm thinking it could be mice that are getting their cage attacking them but the previous years we did not have any problems with the mice attacking the quail. If you have any clues what could be doing this to my quails please let me know.
