What is this?

I thought it was scaly leg mites but a previous veterinary assistant/rooster rescue friend pointed out they aren't really raising the scales and are hitting the soft spots of the feet... So what is this so I can treat it properly?
(I am working on getting licensed to become an official non profit rescue, and have been trying to take on the sick, injured, and elderly, I want to be an avian vet and look forward to a challenge of patience and constantness of treating a bird and the happiness of the bird and the adopter if I am adopting them out which this pair has an owner waiting after they are treated) they were surrendered by a person who took them from someone who was neglecting them and didn't raise them properly
Today I soaked their feet and got the poop from beneath their nails and discovered bumblefoot as well which I am treated as needed, along with a few nails needed clipped so I did that and I wiped below the females vent and tomorrow they get baths and another gentle scrub and soak

You did an excellent job getting the mudballs off the toenails, they can harden like cement sometimes. I believe you're dealing with scaly leg mites and possibly footpad dermatitis at the same time.

Thank you and it wasn't mud, it was poop, it looks more like bumblefoot also, I mean the yellow crust on the bottom of the foot?
