Hello. I’m new to BYC. I have nine hens; not all are laying. Any suggestions as to how to find out which ones are not? Two are 2 1/2 years old the rest are 1 1/2 years old. I’ve tried sitting out in chicken yard watching coop, but I think they are on to me.
You can use food dye (or supposedly even different shades of lipsticks) on the vents to "mark" the eggs. Though I can confirm a watched hen WILL lay... they might give you the stink eye for a bit, but they'll eventually ignore you and lay anyhow.
