I read it, very informative. I can't help but feel like the wet conditions near the water trough in her pasture are the culprit though...being that she's never had this happen until now, and it happens right after she gets moved there. Her diet has nothing in it that could cause it. It's very low fat, and she gets nearly no grain. Just enough to feed with her supplement. Plenty of hay.
She was overweight from being on 24/7 pasture, which I did because she had just come from a barn where she was in for 20 hours a day and it was driving her nuts. She started to get a little too pudgey, so I took her off that and had her be in 12 hours, out 12. She gets plenty of exercise (3-4 days a week moderate and correct work), so she's also building muscle as she loses weight.
Either that or the trim is bad. I've tried to educate myself more on feet, but I keep hearing all sorts of different opinions. If it's a bad trim though, I would love to know so I can try to find a better farrier. I'll get more pictures of her feet so maybe you guys can help me.
