Do you free range? They may be laying in range area.Out of my flock of 83 birds, I’m only getting about a dozen eggs. I know winter slows them down, but it wasn’t much better in the summer. I have various breeds ranging from 4 months - 6 years. What are your guys’ methods for choosing who to thin from the flock? I’m thinking of getting rid of any above 2 years old, and any who is not in good health.
Sounds like a good plan...depends on your goals and management plan(oh, maybe you don't have one

I have space for winter quarters for only so many birds, so hatch and cull every year.
