I noticed today one of my girls had one of her wings hanging done, upon further inspection I noticed a very foul odor, which smelt like death, more to the point rotting flesh, yuck. I picked up her wing only to find out something had attacked her also (I lost three girls to something unknown). She is injured to the bone, it is exposed. What can I do to help her? She appears fine other wise, eating very well and if I didn't notice her wing I would have thought nothing of it because she is acting normal. Thank you for your help in advance. The other girls aren't attacking her or bothering her in any way, so I left her with the rest of the flock.
