I gave advice to some who needed to measure for a blanket for the stallion. He needs a blanket because he is in a paddock with no shelter because he cannot run in with the herd. It would be cheaper just to geld him and toss him out with the other horses, IMO. They don't breed him, and he sits in his paddock all day for a majority of the year. I'm fairly sure he's grade, and not even impressive to look at. (I've seen him before, and the fact I don't vividly remember anything about him generally means there was nothing to remember.)
Some people, I swear. They don't breed him, but they won't cut him. Only times he gets mares is when he breaks the fence down. A few years ago he even covered an old mare who died in result of the pregnancy. The horses are in decent shape and have food and water, and ample shelter (aside from the stud) but I think a little more responsibility is in order.
I have a foal on the way, but the mare was already bred before I got her, and she is getting the care that she needs, not being left in the boonies to fend for herself.
