I would do the elizabethan collar. Do you have some paper cups and tape? I have one on my dog right now, he has sores on his head and it stops him scratching. I would cut the base out of a paper cup, or cardstock, in a circle and wrap it around the chick's neck and tape it there, then put on some furacin or betadine if you have it. Even with socks on that chick is probably still going to try to scratch itself.
Good luck, hope that baby gets better.
