I hope that she gets better now that the shavings have gone through.
When I got my babies I got wood chips, biggish ones, for their bedding. Then my neighbor, with whom I was sharing chick raising activites, got a bag of shavings and I used it when I was ready to change out their bedding.
Later that day I noticed one of the chicks with a gigantic lump in his crop looking as pleased as punch. I felt it and it felt like popcorn and I asked him what had he eaten! Yup, shavings.
Fortunately he passed through this with fresh grapes, youthful digestion and thin shavings but I took the shavings out and went back to chips. They're not too bright, our chickies.
I hope that now this has passed she'll feel better. I would mash up an egg yolk and make it really runny so she can absorb some nutrition. It might not hurt to give her some applesauce or some grapes to help move things along.
Then I'd switch out the shavings for the chips or something chunkier. Just don't get cedar. My feedstore has both shavings and wood chips. I use shavings now in the coop with the adult birds. They at least know not to eat them.
Good luck, Mary
