Our oldest ever hen was 7 ½ when she died last year. Blue Orpington who had never been sick a day in her life then suddenly went downhill. So 11 is a pretty amazing age Shep53 and even more amazing is that she has successfully hatched a brood -a process that needs a pretty fit hen anyway! Sounds like she still has a few more years in her, but tell your friend I wouldn't advise she pushes her into more hatching. She needs to retire and take it easy.
