We have been raising chickens for eggs for about 6 years. We originally started off by purchasing 12 leghorns from a caged farm who were going to dispose of their 2 year old chickens. They have been fantastic layers and 6 years later - 2 are still alive and still laying a few a week between the 2 of them. From there we have purchased a few new flocks . We haven't bought babies for a few years now.. so out of our 20 chickens - the youngest are about 3 years old. Production has slowed tremendously. We get about 6 per day out of the 20 chickens. (if that). they have all molted several times. They are free range, come in at night to the barn to roost. have boxes to lay in the barn and are free of mites, etc and are very clean and healthy. but are not laying! My husband wants to ax them - i don't because we still get eggs! but i also don't want to add new to an older flock who seem to be all set in their ways. Has anyone ever seperated an entire flock into a seperate area and started a new batch from scratch. I'm thinking we just send them to the retirement 'field' and let them have their seperate spot and bring in a whole new batch to start fresh. how do others handle multi age groups. also i don't want to crowd them. adding more to the current roost area and layer boxes (we have 8 boxes) adding more may get too cramped. (even though they can free range but a rainy or hot day they do all hang out in the barn) any thoughts?
