I have one young POL pullet, I don't think she is laying yet, and have had maybe five from a regular layer 2 yrs old) in the last 3 weeks. I am desperate to get the incubator on, but she is stubbornly refusing to lay! Any ideas? I don't want to put up lights on timers as all my other breeds are now laying full swing so I know it's not a daylight issue.
