So she continues to be lame, I am not sure it is worse. I have ruled out bumblefoot. It seems the injury may be above her hock or on the thigh. Her feet do seem more curled and when she sits, she seems to have trouble adjusting the leg, eventually she will thrust it forward to sit.
She continues to lay eggs. And she will climb up to roost.
Today I built a smaller dog size enclosure that fits inside the coop. My thinking is to keep her near the other 2 hens, but limit her mobility. She has 20 inch x 18 in. This allowed me to get her water and food inside with minimal hassle. I crushed a baby aspirin in about a quart of water (81 mg). I also cut a Centrum Multivitamin into 1/3rds then crushed it into her food. I am also giving her plenty of greens which I hope will help with inflammation.
With regards to Mareks. She was hatched last April, so she isn't even a year old. I doubt she was vaccinated, but I will check into that. She is only "splitting" with one leg. Pushing her right one forward. However, she is still walking under it. She only pushed forward to sit down. She has no problem eating, her eyes look fine. I haven't seen anything in the poop, but now that she is more isolated, i will be able to distinguish her poop from the rest. When I pick her up she will initially splay out her wing feathers but this seems to be a normal reaction with most of the hens I've owned. She very quickly relaxes and the wing goes back against her body.
In reading through everything, I believe she either has a high sprain, minor bone fracture or Mareks.

Eggcessive noted that my Maran had a large/odd crop. I have been paying attention to her and see is fully emptying at night and looks normal in the morning. As she fills up during the day, her crop gets larger and sinks to the right. I've made up the diagnoses "Crooked Crop" for her. Curious if anyone has ever seen this with their hens?
