I have a nubian/boer cross doe who has been bred 3 times. First she miscarried. Second had a normal delivery and third couldnt deliver her huge buckling and needed an emergency section. All with her previous owner. I am wanting to breed her to a much smaller buck but I'm not sure about it since she had a hard delivery with her last that ended in a ceserian. What would her chances be of having a healthy vaginal delivery if I bred her to a much smaller buck? He is a gorgeous nigerian my sister in law owns.
