My layer chickens are laying, but the number of eggs is significantly lower than what I anticipated based on the breed and their age. I'm providing them with commercial layer feed and ensuring adequate water and space. The coop is clean, and the birds appear healthy, though some seem less active than others. What factors could be contributing to this reduced egg production, and how can I optimise their laying performance? I'd appreciate specific, practical steps I can take to increase egg production naturally, focusing on feed management, environmental factors, and flock health.
