Ok, so you're not feeding scratch then and are instead feeding a whole grain layer food served wet.It's a scratch, layer feed that I give them-
New Country Organics Soy-Free, Corn-Free Layer Feed. I soak it and they get 1/2 cup each daily. They're not hungry, I can tell by how they eat.

I got 3 eggs for the first time today so maybe they just needed time.
Hopefully you continue to see more eggs from here on out!
