Hi
We have a similar problem. Although our foal is still on his mother, we have given him a lot of attention from birth and have handled him every day and sometimes twice a day. Now when he sees us coming, he gallops up to us and assumes a very threatening (playful maybe) pose almost demanding to be played with. He is just 4 weeks old today and very coltish already. In fact the other day when we didn't do what he wanted, he turned and kicked out. We are thinking that he needs to be put out with the other older foals and mares so that they may teach him some respect.

yes i would do that... Rose is a year old now and getting big. She was ok with me and her owner but she is very agressive towards anyone she doesnt know. She has nearly done a few people a serious injury and it will be worse as she gets bigger. Sadly i dont have anything to do with her now as i fell out with her owner but i hope she is doing ok

My friend recently brought a 3 year old that was hand reared. I don't know how she behaved previously at the stud but in the last couple of months she has badly kicked two people and shown very jealous behaviour whilst we are in the stables next door with other horses (kicking out/teeth showing etc).

where did she get her.. my Rosie would be a 3 year old now
