If your right there with them and they are all safe, why do you have pictures of your 23" yearling filly standing directly next to him, nuzzling him, He could hop right on her. Furthermore, she is not tied in any manner in any of your pictures. theres also another picture of her with her ears pinned back, and him apprehensive throwing his head up. Here's a newsflash - the yearling is old enough to breed! There are lunging pictures with horses who have lunge lines tangled between their legs, your two year old filly is tied on a long lunge line, but its QUITE obvious that line is more than long enough for her to get to the stallion. What your going to end up with is a stallion and a two year old filly breeding, both getting hurt from being tangled in your tie out lines, which are far from safe. Your not going to be as fast as you think you are, even standing a foot away. What are you going to do, lead the stallion away, when there's two other horses there, one isn't even on a lead? If they are showing to the stallion, they may like the idea of breeding, and may follow you. A mare can hurt you too you know. Are you going to be the one man show who can miraculously untangle a stallion who's breeding your two year old, while all three of them have ropes cutting into their legs from being in a tangled mess? Ever see a dog tied out tangle it's self around a tree, imagine three horses tangled around each other, and you already said your parents don't help, so what exactly are you going to do?
I dont for a second think your too young and naive to know proper horse care, safety, and management. Im honestly not all that much older than you, and I can tell you that I certainly knew better at age 15 than to be doing half the stuff your doing. I think you have it set in your mind that your going to breed your horses no matter what anyone says, and just tell everyone here that you aren't to keep the heat off your back. Then when you have bred mares (that i'm sure you'll intentionally breed) you will come back and say it was an accident. Also, please don't go on and on about how experienced you are when your later posts show how inexperienced you are. No one is judging you for what you dont know, you are judged because you try to come off that you know more than you do, and if you know so much, why are you doing such dangerous things?
Everyone has given you more than enough advice that you simply don't want to hear. Why bother even asking for advice if your not going to take it? Maybe im simply annoyed that you often get passed off as being young and not knowing better, when I realize that at your age, you do know better, and just act young and naive to gain forgiveness.
