If she keeps getting pregnant DO NOT put her with the male...simple as that. And for her to be pregnant already again...is going to cause her troubles. I suggest you DONT put them any where near each other till they are fixed!And even after that wait 2 months because he can still impregnate her. Please stop its bad for her and good for people who eat bunnies(and yes these guys would be good size if they are mixed with a wild bunny...)
Or snake food wich is a worse way for the poor baby to die because it will most likley be alive!

As for the baby with no tail he will be fine I know bunnies that have been born with no ear and are fine , it's just a defect like humans get.

Welcome to PT it is great here but when you post about irresponsible sttuff some people including myself get very upset about it. Your Dutch boy dose look very content laying in the grass and seems you take good care of them (except for the babies)
