I bought a 9 yr old gelding on July 23. He was pastured with two geldings for two weeks. He was getting picked on a alot (bit marks and such) so I moved him in with 4 mares. On Tuesday, August 7 (after spending just 2 days with the mares) I pulled him from the herd to ride. Tied him in the barn for grooming and saddling. He was pawing kicking and pacing. After about 5 minutes of this he ended up rearing, hitting his head, and getting stiches. Im guessing he was upset cause none of the girls were with him. By Thursday he starting breaking out in hives (thinking allergic reation to the antibiotics) he is still in with the mares. By Saturday the hives covered his body a LOT. Still with the mares. Vet gave recovery shot. By Sunday, hives were still bad and so the vet gave him steriods for a few days. Still with the mares. By Tuesday, August 14 the hives were gone. Still with the mares. Now its been just over a week, tried to ride and was pretty naughty and anxious to get home so we decided he need to move out from the mares. Now the geldings he was patured with first are gone so he went to his own pasture. After a day he started to settle down, but his primary focus is still "where are the girls?" Today, we brought one of the geldings back to try and get him focused on him instead of the mares. We turned the mares out into their normal large pasture. (We kept them closer for the first few days so that they were always visable.) When he saw them take off, he started running the fence line.... again. Didn't even care that the other gelding was there with him. Im just looking for some feedback on how long this might last. It's total stressing me out!! Thank you!!!
