I dont know how far you are from me in NH but if you would like to come up to our house we have a 3/4 acre training pen for the pups. I dont have any rabbits down right now. If you wanted to you could bring her up a couple days a week for some excercise. When you get a chance pop in and I will show you around.
So far I have not yet had a c- section, (knock on wood). Although my last bitch I had to give oxytocin to because she never got the pushing pains and dragged out the beginning stages of labor for three days

I know what your saying about those big blocky heads. Blackey has got that kind of head, and we are always prepared when we got Fat Buddy pups coming into the world. I have not lost a pup since June of 03. I had a couple close calls since but now have a bit more experience. Either way I think it is just as stressfull as being in labor yourself

Just send me a PM if you want to get together sometime.
You take care and good luck on your pups
