Yay babies , I want to see pics when they come!!!!
oh man now I want to go buy bunnies and put them with the chickens and ducks
I have a lion head but he's a spoiled house bunny!
I'm sorry that your babies died. This may sound like a lecture, and I really don't mean it to, so please, bear with me. The wild ancestors of domestic rabbits dig burrows, so the babies are born underground, where it is warmer. Your doe evidently lacks the instinct to dig a burrow (or else the ground was just too hard). If you have snow on the ground, the outside air temperature is too low for baby bunnies to survive, whether the doe pulled fur or not. Newborn bunnies have a hard time regulating their body temperature, IMO the only way those kits could have survived, would have been if you had taken them inside as soon as you spotted them. I live in a much warmer climate than you, and yet I had to lose many, many winter litters before I finally learned to do this. Once again, I'm sorry it happened.
Make a note on your calendar, because your doe will kindle again in 28 - 32 days. Rabbits don't do a typical "heat" cycle, but they do have hormonal ups and downs. A doe hits the highest hormonal peak she will ever experience, immediately after kindling. Her hormones were already rising before she kindled, that is why the buck was after her. If a fertile buck has access to her, the doe will re-breed within hours of kindling. She will "fire" a bunch of follicles, so expect a BIG litter!
