uncoordinated 6 year old horse

Question
Hello, I've been ridding for years now, but I've never had a horse so uncoordinated. He is a thoroughbred 17 hands high. I just got him during the winter and he was very lazy and skinny. I've been feeding him beet pulp, complete 10, and senior feed to fatten him up. Now he is full of energy, and very uncoorinated. In May at Night i went to go feed him and he had a huge chunk of flesh hanging from his neck. We didnt get him stitches we just healed it up ourselfs, he had a major scar but it better now. When i go to 4-H he trips when I load him up , i use to let him turn around to get him out of the trailer but he would actually jump out instead of walk out, I know he is going to get hurt so I am backing him out now. but he gets scared of backing out and falls out. He is very clumsy horse. I've been using a hackamore on him because everyone tells me he has his wolf teeth so thats why he doesnt take the bit. so i took him to the dentist to hear what he has to say, i found out that he doesnt have his wolf teeth, but he still flips out when i put the bit in, but i think he'll get use to it, hopefully. He has turned out lame when i  got him shoed so i didnt get to ride him for like 3 weeks because he was limping really bad, but we put a pad on his hoof so he is better. but now, he must have wacked his leg on the trailer or something because he has a huge hard bump on his leg below his knee, it is infecting him from troting and loping, he has to get better soon because the 4-H rodeo is coming up soon, so i dont know what to do there. now today he was rolling in the dirt and got his hind hoof stuck in the fence. he is fine but he has a nick on he's leg and a 6 inch cut on his side. Also my neighbors say he is very aggrestive, he has tookin out a fence, rears up to the other horses, snorts alot, and would rear up on fence post and slam down on them... but he is major caring, a serious teddy bear. I can do anything to him. he isnt aggresive at all! What should i do to help my uncoordinated horse, he cant be so clumsy. Please answer my question! please i need some answers on what i can do for saving my horse!

Answer
You need to do better research before you ask questions. I am the wrong guy to ask questions when you want to blame and call your horse names like lazy, clumsy and saying he flips out.

He does all this because of you. You are causing it and can't see since you are too busy blaming the horse.

Had you read my site or watched my videos you might learn something, but instead you are sending out random questions looking for an easy answer for all YOUR problems, you horse has not problems.
