I've got one chicken who lays. The other 2 simply won't. They're all 27 weeks old. The Plymouth Rock who lays started at 23 weeks.
Is there anything short of grabbing the other 2 by the neck and squeezing down their bodies until an egg comes out the nether end that would "encourage" them to get down to it?
