If you spray with blu-kote---do not spray it all over the 'feathers" be careful to spray just the skin. We do not know---what will happen---and I would not put her back if there was blood, raw meat, etc. If feathers is all that's missing I would have to try it.I will make sure to buy some blu-kote before attempting it. Do you think the other chicks will pick on her, if mom accepts her? She is kinda freaky looking! Lol
