The chap I buy my hay from was down last week and we were having a wander round. He said that when they prepare the barley for sowing, they put it through a riddle and use the big seeds for sowing and the little 'uns just go in a bag. He asked if I wanted them for the chooks.
We feed mixed corn in the afternoon, but it's wheat and maize (I think). Can I safely feed whole barley instead? The barley hasn't been treated with anything.
