You know, the more I think about it, and I think about it a lot cuz it is gross .. ( just joking) - all my little chicks this spring were in pine shavings so I could not see each individual poop. BUT- when I cleaned the dry poop from the shavings it was mostly little squiggles like that. Not as long, probably because it was broken or stepped on. Just keep an eye on her and make sure she is getting plenty of water and food. If she starts being extremely lethargic or not eating/drinking - that is something to worry about.
