What is this?

That looks like a very bad case of leg mites, sometimes called tassel foot, when it affects birds, and this is a bad case that has caused the growths and may affect the circulation. Ivermectin would be a good choice to use on the back of the neck down the spine. Dosage is 0.1 ml per every 2 pounds of weight given once and repeat in 14 days. Toss eggs for a month total. I would also soak the feet and legs in warm Epsom salts or saopy water, and use a soft toothbrush to loosen the scales. Apply vaseline or a thick ointment and rub into legs after. Repeat a couplemof days a week.

Just curious...what are the growths typically made of? I didn't even know tassel foot was a thing!

I don't think that's scaly leg mites, but maybe...never heard it called tassel foot.
What ever it is, it's huge!
Gonna take a lot of soaking and picking and maybe cutting(well away from the leg).

It is called tassle foot in birds, but it is the same might and disease:

So this is her foot after we have the scabs.. should we cover it to keep it clean? they’re free range and have a big area to roam and we live in scotland so the ground is very muddy and wet right now ..

Looks like a mass of infection.
I'd keep them covered with antibiotic ointment and keep her confined to keep wounds clean and free of more infection.

I've never seen anything like this but after seeing that last pic I agree with @aart about the infection.... If it is infected, that is likely affecting more than what you can see visually and I'd think oral antibiotics or an injection in addition to topical antibiotics would be critical. I'm fortunate to have a local avian vet, so I don't know what you're able to buy on your own, especially in Scotland.

Gosh that looks painful, but you have made a lot of progress. Can you get an oral antibiotic locally? I would use the Terramycin spray as the label says. If plain Neosporin or a similar ointment is available, I would apply that. You may need to dress the wounds or keep her on a clean towel each day. Let us know how she gets along.
