Broody doesn't seem to fit your hen. She would still be able to walk, if she were broody.
Kathy, do you have any brewers or nutritional yeast available to sprinkle a little onto the egg you feed her? That stuff is packed with B-vitamins. It would be nice to see her get back onto her feet, so that she doesn't permanently lose the ability to stand. Do you help her stretch out and move around her feet & legs, every so often? I don't know how that's done, but I remember last year someone had a "fallen down and can't get up" hen - they gave her some therapeutic assistance with leg and foot stretches until she regain the use of her feet.
I feel for your little EE. My EE is the bottom of pecking order and the smallest of the flock. I have to sneak a handful of mealworms to her, now and then, because she's pretty pathetic at foraging compared to our megatron-foraging machines, like the BA and BR. My DH said to me, today, that Zsa Zsa (that's her name, LOL, he named her!), might not be alive if I hadn't spent so much time boosting her nutritional intake. She lays a medium to large green egg almost every day, too. Still, she's the least amongst the bunch. And very timid, too.
