Left leg won't work!

[3FandWB]

Last Tuesday, (1 week ago), I noticed one of my girls walking funny. Like she was drunk. Wobbly front to back and then she'd just sit back on her bum. Then Wednesday eve, I found her lying on her left side when I went to lock the girls up. (I have 9 backyard hens). Over the last week - her left leg does not work, her wings work as does her right leg. She is not egg bound, but when I withdrew my finger92 different days), she had explosive, mostly liquid stool. I've had her quarantined on my screen porch in a crate with water, food, and towels to keep her mostly sitting up. PediaLyte w/ a syringe, calcium, vitamin B - along w/ cooked and raw egg, dried meal worms, figs. When I try to stand her up, she falls back on her butt. Is this Marek's? If so, should I have her put down? Is there any other treatment?

Sounds like Mareks to me. I generally give them a week or two to see if there's any improvements before culling.
