Yes it is true, but if we have a winter like two years ago , I'll be to busy shoveling to collect eggs! I will just keep 10 fresh pullets, plus the 7 older girls, that leaves room for 7-10 fresh pullets for the following year.By then the oldest girls will be 4. How long does chicken live for if not lost to predators?in my experience young hens, just born now will lay through the winter while your others aren't. I really like that!
