Very good idea. I was accidentally touching wet vents up to 2 weeks before they started laying.First check their vents.
A laying bird (or one very close to laying) will have a moist, pink vent. A pullet who hasn't started/isn't close yet will have a smaller, dry vent.
You can also check the position of their pelvic bone. Can't find the article about that, though.
