Sorry for the delay in getting back. I took her into the vet, who I adore. After looking her over and discussing her symptoms, she felt in her medical opinion that Mary-Kate had Mareks. Bumble foot was also present but not the reason for her decline. To save MK from a long suffering death (which she had as already showing signs of depression), we made the choice to send her off with the chickens above. She was sent to a local creamatorium and her ashes will be spread in an orchard in the sun. Thank you all for your assistance with my many questions! Love this group! My vet also follows this page as well and noted that it was a wonderful resource for chicken owner

. I let the rest of my girls know the news when I got home, but her sister Ashley came to my back door today to check and make sure I wasn’t holding MK in here still like I had all last week. It’s weird and sweet to see animals show feelings. Anyhow, hopefully this thread proves useful to someone going through similar issues.
