Sorry to hear about YinYang. Horrible situation to have to work through. At least you gave her a chance and are willing and able to give her a quicker end once you see it's not going to work out.
About the lime, I have a suspicion it helps with lessening the impact of the Marek's shedding in the environment, because otherwise I surely must have had more cases due to raising chicks on the same soil Marek's carriers, hundreds of them, occupy premanently at all given times. Using calcium carbonate (same stuff that's labeled for adding to their feed) you don't need to move them anywhere, just throw it down. I used it around them at all times. Sometimes they'd go digging in it, once a chook ran in the way as I threw a handful, got some in its eye; blinked it out and was fine, no pain, no damage. It's pretty darn safe stuff, though of course inhaling large amounts of it would not be good.
Best wishes.
