My chicks are 4 weeks old. I bought some Publix brand of Grape Nuts cereal, thinking maybe I would like it now (I didn't many years ago). Nope, might as well go chew some dirt. Can I feed it to the chicks as a treat, or is the barley too difficult for them to digest? I thought I read that about barley somewhere, but I could be mistaken. I just hate for it to go to waste. I guess maybe the wild birds might eat it if the chickens can't. The first 2 ingredients are whole grain wheat flour and malted barley flour.
