New 7 week chicks and Hurt Sigyn

[TinyBoxTim]

Today i got two 7 or so week chicks from a local private owner and one seems to be having problems. One chick is fine and moving around but the other has something wrong with her foot. I am assuming it is because the small chicks were in a run with several adult hens and a couple Roosters. Her poor foot has a shriveled black toe and the other toes are swollen on the same foot, she wont put weight on it either. any suggestions as to what i should do to make her more comfortable? they were the only two choices from the 7 week clutch seeing as all the rest were roos.I'm worried she's uncomfortable and i might need to read up on ex battery hens to provide the right care for her.

*update* i examined her foot more closely and there was very tightly bound thread binding her toes together, only one is fully dead, i had to clip and remove the thread from inside of her middle toe and pull it from very deep in her skin, ill post updates as to how she recovers.
