When do you find that chickens really start to enjoy treats? Ive fed mine various things since they were ~1 weeks old. They haven't really been excited over anything. *sigh* they peck at almost everything but they just play with it.
I gave my tinies (they are 4 days old, lol) a tiny bit of uncooked oatmeal for them to play in. And oh man, I am the wonderful foods givers person human.
