I bought 4 pullets in spring of 21. They all layed just fine for the first year. In winter 22, one of them molted and her feathers never grew back. Never laid another egg. In June of last year, I introduced new chicks including a Roo. 2 more of the hens immediately stopped laying and never restarted. One of them died from an infection in fall and the 4th hen that was laying got caught by a hawk. So, I assume the featherless hen has a health issue that impacted egg production. Maybe the infected hen too. But what about the one that never laid after last June that shows no signs of illnes? She is a Cream Legbar. They are all fed Layena pellets and fermented Scratch and Peck, and free range most days in the afternoons. Thanks in advance for your ideas!
