We use to have 2 roosters (son and father) but recently had to find a new home for them. Now 4 of the hens seem to think I am the Big Kahuna and they squat often for me...they spread out their wings, squat, I put my hand on their back and give them a little shake, remove the hand, and then they shake and off they go. It is the funniest thing. Often they will come running up to me. Is this normal?
