I just changed our feeding program from 90% scratch/10% feed to 100% layer feed. I'm hoping this will spur egg production (I got NONE yesterday for 40 freaking hens...). I also upped the amount so they have 24/7 food access. How long before I should see results? How long does it take for the layer feed to take effect? It's been 3 days, I'm trying to be patient, but I'd like to see SOME improvement.
