8 month old hens not laying

[Aurorareddancer]

We have about 20 hens we hatched in April, most of whom have nice big combs, but aren't laying. We're stumped. Did we raise duds?

If you don't have a light in the coop add one. I think they need 14 hours of light a day. That should help and you're already doing that then just keep feeding and wait because they may be waiting until spring. Are these chickens from a breeder or a hatchery?
