My current flock is 8-9 months old. I don'r expect they will molt until next fall. I plan on getting some new chicks this spring. Plan on them laying while the older ones are molting. Has anyone else tried this. Can they be kept in the same coop. My are free range 2 to 6 hrs a day and penned up at night. I do use a light from 5 AM to 8 AM and seem to help with egg production.
