She's still hanging with us, but the same. Normal for a while, then back to the yellow runs. She eats and drinks but not much. I got a new bunch of chicks and she has been staying close to them in this stall set up in the barn. It's been 2 months since I started this thread. This past week she is laying down more often, and I do sit her in warm water which she seems to enjoy if her bum gets too nasty. The poop dries like concrete then pulls at her feathers. She is thin, but not emaciated. I was hoping the chicks would peek her interest and they did, but this week though she's not coming into the stall much to look at them and she's not getting on the roost at night. If I place her on it she will stay, so I think she's loosing strength.I'm contemplating culling, but I have no way of knowing if she's in extreme pain or just weak.
I honestly didn't think Dixie would live this long, but now I have to think of mixing the flock or keeping them separate - they are 5 weeks old now and I've extended their pen to half the 12 x 12 stall. Cocoa has shown no real interest in the chicks at all, just looks at them and moves on.
This was June 18th - Cocoa, 7 yr old healthy non-laying cuckoo marans and Dixie, 9 year old ailing Wyandotte looking at the newly hatched chicks:

Thanks for everyone's advice and warm wishes. I don't really consider my chickens pets, but 9 years is making this one pretty special.
