It does happen. The main thing is that bat stallions won't approach females. They see it as demeaning, that one should come to them so that rules out 90% of women.

The ones who really want families though will likely be able to get one by approaching a bat stallion. They are incredibly 'easy'.

Buuuuut the woman in question will only give birth to bat ponies so this only takes the family-oriented women out of the gene pool.
