Not just the dead foals either, small breeders with a mare due in December might be looking suspiciously at their mare in mid sept and saying is she or isn't she in foal. The option to get her checked by vet is not viable- you spend upwards of $100 to try to save the $38.50. Increasingly they then review all the other perceived wrongs (too costly, easy ride for some into semis etc) and decide not to pay up for any of their mares.
