Okay thank you for clearing it up, I got a little confused on how many opinions people have, I want to try and avoid and issues if possible and have happy healthy hens!Purina Layena feed is just fine.
If you have laying hens please feed them a layer type feed.
Everyone should spend time reading all of the emergency threads and pay close attention to the ones that involve shellless eggs, reproductive type disorders, and stuck eggs.
Pay attention to what that person feeds their bird.
What you feed matters.
My birds are five and a half years old and they eat layer feed. I have never had an eggshell issue of any kind.
