I was really, really REALLY hoping it was "just" a vitamin deficiency that caused Ethel's paralysis, and not MD. But having said that, she is mobile again, and that is a minor miracle. When you get a chance, can you post close-up pictures of both of her eyes?
Also, can you zoom in on the bulge under the EE you are referring to? (BTW she's very pretty.) Granted I don't have a great eye for looking at pics, so maybe someone else sees what you are referring to. But I don't see anything, unless you are referring to the bumps between her eye and her beak.
I'm also sorry about Dorothy, and I love the reason for her name that your husband gave her. That was a perfect name.
Finally, Im also sorry your mom purchased more chickens at this present time, because you already have a lot on your plate right now. Ive wondered, who takes care of her flock? I know you are doing the intensive care, but are you also gathering eggs, feeding, watering, and tending to them day to day?
