funnies50, I have two Florida White does that just kindled. Both were bred on June 8. One delivered six kits on July 9, the other delivered seven kits on July 10. I think that's 31 days and 32 days.
I'm sure you know more about this than I do but I put the nestboxes in on day 28, along with a good supply of oat hay. The doe who kindled first started playing with her hay almost immediately. The other doe pretty much ignored it until the day before she kindled.
My understanding is that smaller breeds, like the Florida White, develop a bit more rapidly than the larger breeds. For that reason, I'll start looking to remove the larger kits from each doe beginning about the end of the 4th or 5th week. I'll probably have all the kits weaned by the end of week #6.
Anyway, that's my plan but I'm learning that rabbits can sometimes have their own plans...
