These decisions are not easy for anyone, at least no one I know personally. If you are breeding, this sort of hen really can't be considered unless she can be bred to a cockbird out of a stellar layer, and if you only have your flock for eggs, hens like this are money down the drain. I would suggest you advertise them for free on Craigslist for someone who wants a lovely yard ornament, if you can tolerate the possibility they will grace someone else's dinner table, or process them yourself if you can. Some chickens are beautiful but do not produce, at which point (and 14 months is plenty of opportunity, they should be laying well at this point) there are decisions to make. If the rest of your flock is laying well, are you willing to feed a non-productive hen for the pleasure of looking at her? Some are, some are not, there is no shame in either.
