My little ones are 2.5 weeks old and for the past week and a half I've noted some behaviors I was curious about. The first is the challenging... Two chicks will flap their wings and chest bump each other. Is this just rooster behavior or do the hens do it to establish hierarchy... Also what's up with the run/flap wings thing. Every time they run, they flap their wings. It's sooooo cute but I was wondering if they are trying to fly or what. I never thought having chickens would be this fun and interesting!
