So this was on my droppings board this morning. it's brittle, i cut it in half and whitish liquid came out (that's what the part is in the middle in the picture). There was also yolky stuff in the poop so it was like a runny poop. My hen is also acting strange. Standing around in one spot for a long time, dozing off while standing up, being slow and not running up to me when i come outside. She's in the nest box right now, just went in. I do things naturally, so no real medications or anything. She eats organic, local layer pellets and free ranges all day. Lays a good egg everyday. What could this be? Thanks for helping!
