I caught him standing with the right hind further back than the left! First time I've seen that!! He still prefers to weight the left hind though. The mouthy nippy behavior has disappeared now that he has room to roam and grass to munch. I watched a video on youtube today about palpating for ulcers. I tried it and he reacted moderately to all the acupressure points. Stall/pen life has been rough on him. He's getting along fine with the mares. They mostly snub him or mildly boss him. He's not impressed, just takes it and goes back to eating or trailing behind them wherever they go. He is not used to our water yet- he was a little underhydrated today- gave him a bit of salt on the tongue- not sure how much he has had to drink but he is eliminating liquid and solids.
