I cleaned the coop today and found a really weird, dark yellow, dried egg. It was sort of like a cashew but bigger. Soft enough to break in half and see the little yolk in it. It had he consistency throughout of playdoh. I've never seen anything like this. One of my hens regularly lays membrane only eggs with no hard shell, but his one didn't even have any liquid in it. Anyone ever seen this? I do have 3 pullets that are maybe starting to lay, 2 1 yr olds that are moulting and 1 that is just laying consistently.
