Agree with you Speed, except for the above. It is treatable too.
OP, I know not your horse, but she needs to see a trimmer/farrier who can trim & manage her feet right. Something's very likely not right there if she can hardly move! She will also likely need a bit more frequent hoofcare, as cushings tends to make all skin, hair hooves grow quicker. Even teeth too, according to some. Along with medication for cushings, a good, healthy diet & protection for her hooves, such as padded rehab boots, until the 'founder' is got under control, to allow more *comfortable* movement.
The orange hair is a sign of lack of nutrition - that may not be because she's not being appropriately fed/supped but that the disease is reducing what she can get out of it. Upping/adding magnesium to the diet will help too.
