I'm just taking a chance that this is the best place to post this. It's not an emergency, injury or illness. But my Light Brahma hen Nancy, four years old, has pockets on the bottoms of her feet that collect balls of mud, pebbles, sand grains, etc, and they stay until every week or so, I dig them out. I've had other people insist she walks funny, like her feet hurt, but she's a huge Brahma girl, she waddles. Have other people had this problem with a chicken? Is there anything I can put into these tiny, but deep, pockets to prevent them from collecting debris? So far, it doesn't appear that the tissue is irritated, but it does look like it would be uncomfortable.
