Neither my ducks, nor my moms chicken will eat this whole.
Note the straw like shell, they don't like it.
As such I have to grind it down, hence the testing today.

Do you have to grind grains for chickens? I feed whole grains to mine. Should I be grinding it?

Slaughter chicken also beef up much faster being fed ground grains.

If Your chicken are more pets than anything else then whole grain is the most natural.
Just make sure they have access to sand, fine gravel, dry dirt as their digestion depends on it.

Chicken (& ducks) also like wood ash and small sized unburnt wood coal like out of a wood stove or fireplace.
I guess OWB ash is the same as long as You didn't burn trash in it.
