I just had an experience I will never forget! My chickens free range all day and when they see me, they come running up...they know a sucker when they see one! I went in and got some treats and came back out and the roo (who is the most friendly and brave) came up and was getting food from me and giving it to the hens...before long they were all eating out of my hand. the rooster stopped suddenly and made the DANGER cluck....all the chickens took off and went under the shrubs by the fence. Just then I looked back and a Bird of Prey came flying over the house across the back yard! My dogs started barking and "chased" the flying bird! I was in AWE! The rooster must have heard the BoP coming? Didn't know my dogs were clued in either! WOW!
