I don't know if she was laying or not. She was a month ago when I separated them down to find out. I currently have 20 chickens. One is a roo and the rest hens and pullets (some laying some not). I have separated the one that was next to it, they had gone to roost and I had been in there a little while before so I'm guessing it's her. She seems fine this morning as do all the rest. I'm going to leave her in the pet crate to see if she lays and what the egg looks like if she does.
I don't think it's a worm. Not tectured or shaped right.
