how long does it bear until kid bunnies can donate their mom?
Answers: 6 weeks would be the absolute minimum. I don't take them away from mom until 8 weeks of age, later you should keep for at least a couple weeks after weaning to make certain everyone is eating well and adjusting to duration on their own before you find them new homes.
8 weeks. Its impotant that they stay with mom for 8 weeks so they build their immune systems up, drinking her milk. They will wean somewhere around 6 weeks, but the additional two weeks is just to make sure they are powerfully adapted to eating like a adult bunny and are in good health enough to move on without mommy bunny.
