I have a decent CL market for them here. I usually change my birds out at the end of their second year (hatched in say spring 2015, start laying in Oct 2015, lay through until Oct 2016, molt and take a break for the winter, start laying again in spring 2017, are scheduled to molt and take a break again around October 2017) but before they stop laying. In the example in parentheses, I'd start selling those birds in late July or August 2017, while they're still laying so the new owner gets some eggs before they take a break for the winter. For 2 year old birds I charge $10 and don't have much problem getting that.
I'd say check your local CL from time to time and see what's advertised there, and what the prices are. You don't always have to go with what other folks are charging, though. I have folks selling birds at insane low prices....point of lay pullets for $7.....but I hold my prices firm and always sell my birds, sometimes it just takes a week or so.
With your user neme, LaPine--is that LaPine, Oregon? Central Oregon has a thriving backyard chicken population so selling hens shouldn't be a problem there.
