Might be coincidence, but Aria abscessed when I broke my foot. A friend looked after her, so she was mostly out 24/7 and she had less, if any, of her (forageplus) supplement. She'd already been getting less than normal of it for the Summer, as there was so much going on with new people taking over the yard, I hadn't been giving it to her every day anyway. It was dry at the time. Since I've had her it's the only time she's abscessed, despite being out 24/7 in last year's very wet and muddy winter. She's just about grown out the abscess hole now, it popped just under the coronet, so it's taken a while to grow down. She's barefoot.
