what causes angel wing and how would I treat it? I have 2 out of 7 guinea chicks that are starting to show the beginings of angel wing, wings starting to stick out ? they are such cute little boogers I would like to do all I can for them, they are getting a medicated high protein game feed. normally I dont feed medicated to game birds but the feed store wasout of normal starter. any suggestions? ok its offical I can not spell today LOL. I posted this pictureon the contest for guineas also but I want to show you what I am see int in a couple of them. thanks.
