This morning i found an egg on the pen floor in the dirt. It was crushed and looked like something ate it then regurgitated it. I found a hole under the post and filled it in with rocks and sand and this morning there was another hole. I think its a snake as the hole isnt that large. Would a chicken crush its egg to look like it was eaten but not eat the yolk? I got 5 eggs from my one tetra but nothing in a few days and i found this crushed soft egg this morning. Wouldnt the chicken eat the entire yolk?
