My rabbit had 4 babies 3 days ago and this morning I heard them squealing. I went over to check on them and discovered that one was dead (I don't know the reason) and two others were missing legs. The that was missing the 2 back legs died 2 hours later. I now have 2 surviving youngs, one untouched and the other one clinging to life. Itls mis on front leg. I do understand that she needs to be with her young but I'm afraid she will harm them. What should I do? And do you think the one with 3 legs has a chance of surviving?
