First time chick owner and it started out so well. Unfortunately, it has ended in tragedy as a predator got all of our chicks that were in their coop! 
We have ONE girl left who was isolated in a separate coop due to a leg injury. She is 7 weeks old, walks with a limp, and is all alone now. She is such a sweet and gentle thing and I need to know what is best for her. Do I see if I can find maybe 3 more chicks? Would it be better to find someone with chickens to take her in? I don't want to do that, I want to keep her and also, she has that limp. Probably won't be good for her to join another flock, anyway, right? Will she do ok with a few younger chicks?
I would appreciate any advice you can give me.
