I'm thinking I might have to try that! I'm starting to get impatient...even though my pullets are only 19 weeks today. It's been horribly hot. They've been "checking out" the nest boxes and occasionally sitting for a minute or so then leaving. The one Red Star that was looking good and red and mature got snatched by a dog when she jumped the coop fence last week. Sigh... I feel like I'll probably be waiting til October or even next spring if I don't try the light trick.
