What foodstuffs include Methionine?Do bear in mind the breed of chicken will have an impact on ensuring they get adequate nutrition. A hen tht lays 300+ eggs a year is going to be more demanding to feed properly than a hen that lays 150 eggs a year. The most likely difficulty is supply sufficient Methionine.
We have an 8 month old Golden Comet who has just starting squatting two weeks ago but hasn't laid an egg yet. Started giving her Calcium Citrate to help with any contractions that might be happening. As a production breed, I am concerned she hasn't started egg production yet. She was 12 weeks old when we purchased her on layer feed from the farmer - not grower feed, so I fear she may have had inadequate feed source for her early development. I immediately switched her to grower and she seemed more satiated. They always have free access to oyster shell and grit.
