I noticed the other day that there were some scabs on a couple of our hens. No one seems to be limping, they all run pretty fast when I go outside. She's been eating just fine and comes for treats. Everything seems to be normal with her other then her legs and feet. Here's a close up. I noticed a few spots on a couple of the other hens as well, but not as bad. There even looks like there are a couple spots on the bottom of one of her toes as well. Does anyone have any idea what this could be and what we should do?
