I've got a set of 10 Buff Orpington pullets. They are 5 months old and should begin laying very soon. Egg production is important to me. They are not pets. My plan is to order my new pullets in the spring and then, when these hens hit 18 months old next September/October, add them to the deep freeze as stewing hens and replace them with hens I order in the spring. Thoughts? I plan to do this every year. I've been told that, for egg production, this is the most efficient method.
