I think I have ruled out maerks disease since my hen only has a short list of the problems. Someone mentioned to me possible scaly leg mites. Both toes are curled up and she walks on her "knuckles" while flapping her wings to move from point to point. She's a 6 month Black Sex Link. I googled pictures of Scaly leg mites and came across a photo of a hen whose head was attacked. My 3 y/o Australope looked just like the photo. She stopped laying eggs when the new hens were introduced as pullets and is only interested in wandering the yard and keeping an eye out for hawks. I'll post photos as soon as I figure this out. Thanks for your help.
