I have several 3 year old buff orpington hens. One of them periodically lays some sort of weird stuff. This happened today. It's an egg shaped and sized thing, it's the same light brown color as the buff orpington eggs, it has no shell, and it is the consistency of the white of a hard boiled egg. This has occurred about 3 times in the last 6 months or so. She hasn't laid eggs during this time I think. Has anyone heard of this or have any ideas what it is or why she does it? I'm not even sure who's doing this - it's one of two. One of them acts sick so I imagine it's her. I'd love to hear if anyone else has experienced this. Thank you.
