I'm not sure there's an answer but out of our five hens, Blondie is the only one that lays a blue egg.... so I know she's the one not producing. She's only 1 year 3 months old and until she went on strike she gave us 2-3 eggs/week. I would consider the shorter days as a good excuse, but it's been going on since last August! She's free range and has the same high quality (unlimited organic) feed as the other hens along with unlimited oyster shell and always clean water and coop. Essentially it's a chicken country club. All the other girls are doing fine. Blondie runs around like everybody else, is strong, and seems stress free. What's up? (Three of our other hens are generic, plentiful layers 6-7 eggs per week and one Marans who even through molting is laying 5 eggs a week.) Thanks in advance!
