We have a buff brahma hen who has awful looking legs, they are very thick and scaly. We were told when we got her that she had those legs just because she was old. But I am seeing legs that look like hers that are 'definitely leg mites'. Is 'old hen' an excuse? This chicken isn't mine, nor is this my photo, but they are basically what our chicken's feet look like. Since we have no photos of my chicken.
