Thanks for the swift replies.
I have fed them this morning on fresh hay and the normal mix all our rabbits are on at the moment and they all look happy nibbling away and taking drink from our water feeder.
My thoughts on why she may have passed away??????
No idea but looking after 5...
Came home yesterday night to find that our big black mom of 5 had passed away during the day. After the initial tears etc.... its now on to the important subject of looking after the kids.
They are about 5.5 weeks old and from what I have read this seems to be about the time they are weaned...
