So, I know that before the summer my buck fathered at least one successful litter, and my doe has had 3-4 litters per year before I got her. I bred my older doe to him in August and got nothing. Bred him again to my older doe, and the younger one in late September. Still nothing... We had a very hot summer and I chalked the first miss up to him still being heat sterile. Now I don't know what to think. Any suggestions? I am really getting discouraged about the whole mess, I know I am new at this so ANY help is appreciated.
