No worse, no better.
I just gave her a bowl of yogurt, an ear of corn, and her own small bowl of water. She ate/drank it all. Not voraciously, but she does seem alert and has an appetite.
Last night, we had her out in the kitchen on a towel. Gave her water. She got her bearings, then took a few tottering steps around. She slid on the wood floor and clucked a little. I decided she was dry enough, so I put her in the roosting house, in the bed of hay - not on the perch. She appears to have bedded down there all nite, as evidenced by the poop. This morning, she got out of the house, which is above ground, with a narrow entrance ramp. She isn't moving around much still - and really appears to be lame - not able to move more than a step at a time. It seems like her legs buckle under her as she takes a step.
The other hen seems fine - maybe a little bothered by her friend's abnormal behavior. She laid an egg yesterday, so it's a gamble whether or not she'll lay today, but that's normal.
I will see if the feed store is open today, and maybe I can look for some type of supplement. Or, I can take her to the vet tomorrow - that choice will be rather expensive, though. We'll have to do some thinking.
This is what the henhouse looks like: she is hanging out on the ground, right next to the ramp. (this is an old picture)

Beatrix is on the right in this photo: We think they are about 2.5 years old and were purchased from a large free-range hen-farm about 21 months ago.
