Oh wow my chickens would go insane over this!!!! They LOVEEEEEE grains! They ALWAYS pic the grains out first and leave the layer feed. They will only eat the layer feed later once ALL the grains are gone. What they basically do right now is this, they are eating the grains out and then the next morning they finish up the food that was left in there. Still having left overs and still working on trying to get it right so no left overs at night.
That IS my layer ration...with some whole grain and boss. That's what fresh ground layer looks like...you just can't see the finer ground bits lying under the whole grains in the mix. In the layer, oats are not always ground and the corn looks merely crushed and then there are finer ground grains in the mix that are like a powder or meal.
