Hi...My sally just resently had 5 babies and has been VERY active. Two days ago I noticed that she was limping and she was not using her back leg. I have been keeping a close eye on it and noticed yesterday that her leg was swollen and twice the size of the her other. Now this morning the leg is swollen to at least three times the size. Does this mean it is broken or sprained? She does jump out of her cage alot on her own.
