Yep they are both fertile and it will happen...the buckling is fertile at this time as I have a La Mancha buckling and he has already bred my LM doe. So if you dont want to lose her I would get some Lute and get it done. It dont hurt them and will keep her alive. I have to do this in a few days as the LM buckling jumped the fence and bred my 1 yr old Nigerian doeling. Yep the 30th she gets a shot of it. I can believe he got over or squeezed between the gate, not sure so I will lute her and then breed her to a Nigi buck in Nov. Better to be safe than sorry later.
