First of all I'd like to say you I think you gave Shellonabeach good advice about her horse. I think it will be better if her horse is closer to her and she can spend more time with him. It sounds even better if she can move two horses together so he still has a familiar face from the old barn with him. Where I went to college it was nice that they allowed students to bring horses and board them at a barn just down the road from the dorms. One of my friends brought her horse and I spent many hours at the barn!

Ok, for the new question it is several questions about my friend's Thoroughbred Gelding who is about 8 or 9 years old and she has had him a little more than a year now. He is a retired racehorse, sweet with people, great to ride, I have ridden him english and on trail rides. He has several issues, some seem typical to the breed, he crib chews, he does wear one of those things that buckles around his neck(I forgot the name of it). He also is tall and thin(17 hands) and hard to fatten up, he is an active horse with a good metabolism. Since he is the newest horse of her 3, he is at the bottom of the pecking order and gets picked on a lot in the field especially by her QH Gelding who she has had the longest who is the alpha horse. He tends to get a lot of cuts etc from the other two horses nipping at and kicking at him. When they are out together they have a run in shelter with food but he may not be getting enough of his share of it with the other two horses pushing him around. He can be put in his stall when the other horses are being worked and I have heard there are extra feeds that can be given to help fatten up thin horses. One other thing with him is he has very sensitive skin which has a reaction to bug bites in the summer, he gets bumps all over, any advice on a fly spray that would help a thin-skinned sensitive Thoroughbred?
So I guess there are 4 questions total about crib chewing, fattening up a horse, pecking order and sensitivity to bug bites. Let me know if you need more details.
