HI there! I have a 4 month old filly that is a sweetheart. I had a person tell me that no matter how much I train her, that when her horomones kick in she will be a brat and go through a kicking, biting, shoving ect..stage. Is this true? I don't want to believe that because she is doing so well with her training. Maybe this person is just being negative towards me or has had bad experiences. What do you guys think? Any succesful horsey people that have raised a baby? Thanks for all the opinons!
