I boarded at a barn for a short while that the owner was an alcoholic (did not figure that part out until later), and she would sometimes mix the herds up, I doubt it was on purpose, but it happened the none the less. At one point a 2yo stud colt ended up out with a group of mares that contained my Paint mare, a larger Paint mare, two TB mares, and a Morgan mare. The two Paints and Morgan were buddies and the two TBs were buddies, it was an easy going group that all got along, until the stud colt entered. He was actually quite friendly but at some point, the girls got into an altercation among themselves that we can only guess was the two TBs (both shod behind) against the other three. The other Paint was no worse for wear, the Morgan was torn up pretty good, my girl had gotten several kicks, one in the hocks. I hand walked her a few days, buted her and got a pregnancy test (luckily, no foal!! PTL).
At any rate, all girls healed up just fine. One of the owners got angry when she saw me giving my mare bute and said "she doesn't need that! It's not THAT bad" and I reminded her that the other night she had taken ibuprofin after a day of cleaning stalls, so she had little room to speak.
