Yes, there is such a thing as “horsefeathers”!
And I’m not talking about the extra long hair around the feet of some of the larger breed of horses either.
The horsefeathers I’m talking about all horses are born with but only have for a very, very short time. That’s probably why most of us don't know about them.

When a foal is born, the bottoms of their hooves are covered with what looks like feathers. The purpose of these so-called “horsefeathers” is to protect the mare during the birthing process. The foal starts to lose these feathers almost immediately as the hooves start to dry and harden.

These pictures were taken within minutes of birth and they are already starting to fall off.
