Im jemma and im new to this..
I have a 3 year old cob who was very placid. We got him from the wild and done everything out self with him. Recently we got him castrated and ever since he has been really nasty to the other horses in the field. They wont accept him and he wont let them get away with out a fight. I have never seen him like this before and im worried im going to have to sell him??!?! Does any body have any advise? I mean is this normal? He has never mounted a mare before he was cut and didnt seem to have the urge. Please someone help me I don't want to have to sell him
