Some eggs broke in my coop and I removed the bedding and put it in a small bucket outside. I forgot to move it this morning and so some of my chickens found it and were eating the egg shells and small pieces of bedding which had the egg broken on them. When I came out to stop them one of my hens had egg shell sticking out of her beek so I pulled it out. Is there a risk of impacted crop? How do I get my chickens to stop breaking eggs to eat? Thanks!
