So I've had two horses born in the past week that haven't shown their fathers in either inspect or examine. For the first one I thought maybe it was because their father had died (I had a male from that pen die of old age and he could have been the father) but I'm sure that isn't the case with the one I had born today! The foals are unrelated, one is a female buckskin 4 speed, and the other is a male blood bay 2 draft. Born today and on the 21st respectively. I've had others born in between that show their parents as normal, so far it's just these two.
