I have 6 older hens in a run with 10 young hens that haven't starting laying yet (they have reached the laying age though). Back before winter I got two tiny eggs that I thought were fart eggs but they had yolks. One was brown and the other blue. I have young and old chickens that can lay blue and both that lay brown. Today I got (for the first time all winter) an egg and it was a large brown one. So, does a young hen always start laying small eggs?
