I was curious seeing as one of my mares is pregnant, while I am hoping for a filly, I want to be prepared if it's a colt. We have one gelding and the rest are mares, and if we had a colt running around I definitely wouldn't want them bred. So how young can a colt be and manage to breed a mare?
I've heard of colts covering mares even before they drop. I plan on keeping the foal on my mare for a good amount of time because I plan on boarding him/her somewhere else when I wean him/her. It would help if it were old enough to get good training in and if a colt get gelded a place that could escape flies for a while.
