Can it be the food? We noticed several things in the last time - some of the Hens and one Rooster look like they are not coming out of molting, it almost looks like the lost feathers are not growing back at all and there are way more feathers flying around then the years before - egg production is unusual low (no rooster overpopulation) - some ladies are now over 7 month and have not started laying yet - they are free range, with pellet food, grit and oyster shells available 24/7, chicken coop open/close at dawn/dusk - no diarrhea, vomiting, lethargy, no parasites We asked the Feed Store where we buy this food and they said, that they have heard the same thing from other customers, too. And after switching to a different food (sure more expensive ;-)), all this would disappear. They recommended 'PayBack'. The pellet food we are using now is locally made. Any thoughts?
