I had my new chickens (2 jap roos and 2 oeg hens) in a cage outside today while I cleaned their coop. My other chickens and guineas were out free ranging. The guineas came over and surrounded the cage and my female guinea started snapping at the cage. It was awful. They dont act like this around the other chickens. Not even when I put an expected hen in the coop. The treat her like she has been there all along. Why are the little ones different?
