I have a 6 year old Pygmy doe that was successfully bred a couple years ago and was assisted by my vet to kid. She had twins that were full term but died in utero. The vet tech had to reach inside her and pull the kids out. I have tried breeding her twice by leaving her with my buck who always gets the job done, for 45 days and she has not taken. She shows signs of heat but doesn't get bred. Could the tech have damaged something when she assisted the birth? Can goats develop hormone problems? Looking for some advice about what I could do. I've head goats for a while but haven't had this happen before.
