Could that be severe bumblefoot? What bothers me is it's on both feet, which is why I'm still leaning towards bumblefoot. What are the coop and run conditions? Are they clean and dry or muddy and feces filled?
They roam the backyard all day, their coop is sand and their sleeping area is clean and is wood chips with metal poles for sitting. Here is the bottom of the foot, it looks like the growth has gone all the way through the foot. Not sure if I should try and soak the foot and then just cut it out myself, or wait until next week when I can get to a vet.
Still looks like bumblefeet to me, poor girl, it must be really uncomfortable having them both bad like that and yes I would start by soaking and trying to scrape away some of the scab and if you can, dig the core out, but make sure you have everything you need to pack and bandage them before you start and maybe just tackle one at a time, but if you are not confident of dealing with them yourself and you can afford it, a vet would probably be best.
I agree with soaking the feet using warm Epsom salts, and removing the softened scabs to get the core out. The cores are hardened cheese-like pus. It may take some serious squeezing to get them out. Then put plain neosporin ointment and a gauze dressing on the feet.
