I was doing chicken chores this morning part of which includes cleaning any poop from their sand dust bathing area. I noticed what I first thought was a tiny soft egg, but closer inspection showed a sort of cord attached to one end - kind of twisted like sausage casing. It was soft and small compared to a regular egg. When I broke it open, the contents sort of resembled yolk and white but more curdled looking.
Any ideas? Since all the chickens dust bathe in this area, no idea who laid it.
