Rabbits have the ability to breed immediately after kindling. In the wild it’s not uncommon for a rabbit to be bred even between kits being born. If you experience a false litter(pulled fur but no delivery) or lost a litter, rest assured you can rebreed immediately. She most likely will eagerly lift for a buck. I rebreed my doe’s when the kits are 4 weeks old and wean at 6-7 weeks.
