What is this? I found this in the coop under their roosting post. We just got a couple new birds and noticed this under where the bird usually roosts. She hasn't layed an egg yet for us (we had her 1.5 weeks). Could this be a egg that broke? It kinda looks like there's little shell peices on it.
It does look like a shell that didn't harden. You can explore various egg abnormalities in this article: https://www.backyardchickens.com/a/common-egg-quality-problems
Looks to be the remains of a soft shell egg...or is there good hard shell attached? Birds in a new place, especially when introduced to existing flock, can be very stressful. It can stop them from laying until the get comfortable in the new situation. When a bird begins to lay, either as a first time layer, or an older bird starting back up again you can get some funky eggs. A soft or thin shelled egg can be easily broken and fair game for eating, often the only sign is a wet spot and maybe some shell or membrane. I'd not worry about it unless you see it with frequency.
