Breeding frustration

At the beginning of October we rebred Kiana, When we tested her a week later she spat and sent the male away. Unfortunately yesterday she was down, letting one of this years cria mount her, did not get up when approached, and one of the other females was chasing everybody else away. Not a good sign that she is still pregnant. It is now to late in the season to rebreed her as only a month before winter would be here so would be tough on a young cria next season.
