I wish I could, Diana, but this is wooded acreage and I don't even know where all the burn piles are. They were all over the place-it puzzled me no end as to why there was pile here and another one there then another one somewhere else and all had glass bottles thrown in them. Idiots! I've lived here five years and tilled the chicken pens and removed soil over and over and still, the girls will dig up another piece of glass inside their pen! And that doesn't count the times when they're freeranging through the briars (cowvine, aka, greenbriar), brambles (blackberries), sharp sandstone ledges, etc. I would not wish my experiences with bumblefoot on anyone-it's truly horrendous. I bet you money that many people have chickens with bumblefoot and dont even know it, never know it, even if the bird drops dead from it going systemic.
