If you can get her in a small pen so you wont stress her out chasing her....Give her a shot of Banamine for pain (cause you know its gotta hurt!!) this is why she is staying away from the others..she needs a place to rest, eat drink for a day or two...Also whie penned up..I would finish her job...it hanging like that can get caught and snagged...BOY that will hurt even more...so snipit off if its hanging...use sharp Nippers..go quick and hopefully one quick snip will do it..if its hanging from a large piece a nipper cant handle there are a wire saw ( I think called bone saw)..Its hard to use IMO and the goat usually ends up pulling away and ripping off the piece..but it does need to be cut off...blukote it again once done..offer cool water and also a bucket of Electrolytes so she can choose..The banamine should help her want to eat but I would also give her b complex...
Best wishes
