I had a foster that did that but it was later so by then she was getting a tad tired frm all those babies clinging to her. Lol. I made her a shelf so she could get out of their reach and that settled it. Thankfully, despite all the trampling the babies had endured, there were no injuries.
Giggles was a very protective mum and she made the nesting as padded as possible and as deep as possible so that Rolo wouldn't get out. Good thing she did too, since Rolo was an only baby and would have chilled very quickly as she was born in October. She was constantly fussing over her! Mama rabbits sure can be sweet!
