When will my hens start laying and should I switch their feed?

16% is the bare minimum of protein they need, 18% is better.
Is the scratch n peck the whole grain or the pelleted? Try not to feed the whole grain type, they tend to pick and choose and end up nutrition deficit. You're doing great!

Thank you! I didn't know about them picking out only the parts they like. I might try fermenting the rest I have and look into pellets. Thanks for the advice!
