So I have this year old light Sussex hybrid and she was a totally normal hen until a couple of months ago when she consistently (and still does) only lay eggs which do not contain yolks. After a lot of research and talking to the hatchery where she was purchased we came to the conclusions that it was her genetics. But anyway I just witnessed her poop this out and I've no idea what it is! I've never seen anything like it, any suggestions?!
