So like you got a lot of good advice on the wound. I don't think I would put her back in with the big birds especially if you think that is what happened to her. If it happens again it might be worse next time. I would wait to put her in with them until she is about the same size as them. Do you have another bird about her same age she can bunk with until they are big enough to go in with the big girls? I wouldn't put her in with anyone until it heals though.
Goodluck
