This morning I went to let the girls out and I found an egg in the poop tray under the perch. The shell is so thin it looks almost more like tinted membrane. Right next to a fat piece of poop. The hen who did this is fairly new to laying. Is it a thing where they think they have to poop and they shoot out a not-ready-for-primetime egg? Anything I can do to prevent this or is it just a function of her being new at this? Thanks!
