1. let rabbit do her job. don't intervene unless necessary. Sometimes takes three days for milk to come in. Babies can survive that long.
2. don't be afraid to foster from one rabbit to another.
3. save fur from any failed litters to give other does who don't pull enough.
4. give the appropriate size litter box.
5. remember...bunnies die.
6. feed mommas enough pellets so they can feed their babies, and make sure they have plenty of water.
7. babies can eat whatever momma is eating.
8. check eyes and cleanliness day 9/10. If in warm building remove nestbox at two weeks.
That's a quick nutshell.
