I'm not sure how it happened, but it was about a week ago, and is looking steadily worse. She 'seems' to be eating okay, but I'm not totally sure. She is a 8.5 month old wheaten maran, though she is very little. Is there any special care I should be giving her? Will it regrow? I'm worried she won't get enough to eat because she does get picked on by the older girls. She is a runt already and had mites awhile back, so not eating would be the last thing she needs. Sorry it's sideways.
