Breeding my bunny

Question
Hi, My lionhead rabbit age 1 and a half years had 4 babies in her first litter last week but she had them down stairs in her litter tray instead of in the lovely nest she had prepared, she was off her food and not pooing for one week before they were born, they all died on the wire before i found them, when could i give her another chance at being a mom?  she didnt pull the hair off her belly either,

Answer
hi annie give her another 6 weeks before mating again.
they dont always pull fur out.
I would not use a cage with a wire bottom its not good for there feet -get on with a solid bottom and put plenty of hay inside -she will be much better with this.
