“Stallions will kill any foal not theirs.”
Special circumstances? Sure. But in general, this is a myth. I can’t tell you how many people have told me this as absolute, general fact … and then I point (still) to moments like this: Comanche with Temple, who not only is not his daughter, she is not in his band. She’s the daughter of Hollywood and Piedra and still is perfectly fine and dependent upon mama – in her daddy’s band.
I’ve seen more ears back and teeth bared from mamas telling wandering babies to go home than I’ve seen any kind of violence toward foals from stallions. I know I tend to repeat this, but it’s one of my pet peeves, and I love when the horses give me an opportunity to show that the opposite is true.
