Why cant you breed your female donkey on howrse If you own a male donkey and they are both old female 8 years and male 3 years enough to breed and she has had no offspring yet?

The only way they are not able to breed is;

1. One of them already has 3 offspring.

2. The male didnt offer a covering reserved for the mare.

3. The male is gelded. ( Meaning no longer allowed to breed )
