I have one Americana hen that stopped laying about four days ago. She has been very consistent up till now - only skips one day here and there once she started laying almost a year ago - and even layed all through winter. She is just over a year old and seems happy and healthy otherwise. All of her sisters are still laying. I have seen some feathers in the run - but mostly from the other hens and it has been very windy - so pretty sure she is not molting. She is pretty much at the bottom of the pecking order and it seems like the other girls might be pecking at her a little more than usual - but nothing drastic. She does not have wounds or bald spots or anything. Maybe stress? I did find what might have been an egg without a shell two days ago in the coop (a big sticky yellowish clump). I wondered if the other girls might be eating her eggs - but why just hers and no others? They have never eaten their eggs before. Any ideas would help! Thanks!
