My hen, Lotty, was looking a bit blue yesterday afternoon, I went over to her and she let me touch her (she NEVER lets me do that). I patted her on the chest to see how her crop felt, it was okay, then I put my hand down and felt down near her vent, and all of a sudden a soft shelled egg popped out! I think it must have not been passing through her, and the little pressure I put on her made it come through. She PROMPTLY perked up! Turned around and started eating it.
