Glad the horses are in a better environment. Had they been my neighbors, we would have offered to help improve their situation. He didn't look all that strong to me, so I can see the job was probably too daunting for him. Of course that's just speculation on my part.
I do pick out my paddock regularly, as well as the stall. I do not do the fields. I like my place to look neat and clean, and I want my horses in as clean an area as possible. I also lime the areas regularly too. But that is me. I am ever watchful for thrush and other hoof ailments. Rather prevent than try to treat.
Be the kind of woman that when your feet hit the floor each morning the devil says, "Oh crap, she's up!".
