I am picking up a new colt who is still intact next weekend. The vet here said they will not geld him until the fall because the flies are too bad, although I'd like to get it sone right away. He just turned 2 in june, and is currently out with two fillies and another stud colt. One of the fillies was in heat when i went to see him and he was trying to mount her the whole time I was there. He is not aggressive to people, but he is chasing around the fillies biting at their tails and trying to mount them constantly. He has no interest in being around people right now and was acting skittish when he is normally very friendly. I am wondering how long a colt will ggenerally keep having stallion "urges" after they are gelded. Will he keep thinking he's a stud because he has already been trying to breed? I have had a stud before but I got him at 4 months and he was out with geldings, was taught to have manners, and was never out with a mare when we eventually sold him at 4 years old. This colt has been "petted" a lot and the owner can pick up all his feet, he does not kick or bite, but he will not be caught and has a bit of an attitude. He is concerned about the girls all the time. I'm moving him to a new facility where there are two mares he'll eventually be pastured with after gelding. I want to make sure he can be kept with them without trying to mount them or any of the horses getting hurt. he'll be stalled until he is gelded, but I'm just curious what other's experiences were with young 2 year olds that have already realized they are "all man".
