The Oats are a good idea if there was a way to keep there protien levels up as far as intake.
I have thrown oatmeal out for the Turkeys and Chickens to eat that was left overs and they will fight over it like crack addicks they love it and some times fights break out LOL.
Yeah there is always that protein fight! I have the same fight when trying to feed my goats but the oatmeal makes a good source of fiber and used as a scratch with some rice bran might be a good alternative to a hen scratch since I can't find anything in my area that has organic non-gmo corn.
