Why is the filly seemingly low down in a stall with no bedding? Why are her hoofs painted? There seemed to be a third person there. Why didn't you both stop the idiot who was abusing the donkey? Or is that the 'mule' you said lives with your filly? If it is a donkey and he whole and if, as you said earlier, your mare is in season, then expect a baby in 11 months.
Couldn't really see your mare at all, since she was too far away. Next time, have someone hold her while you take the photos. She is halter broke, right??
