Buff Orp with sores on feet and legs

[tampitt]

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?

You might look up Bumblefoot under the sticky at the top of this section titled "helpful references". You can also link to it here https://www.backyardchickens.com/forum/viewtopic.php?pid=2797594#p2797594

Those don't look like they are on the bottom of the foot, but some of the information may apply.
