I've got 3 babies...probably around 4-6 weeks old. During the afternoon I take them to a fenced in 5 ft x 5 ft square of land and let them run and play. Today they were jetting all over the place, flapping their wings and having dust baths. I noticed several times they would run at each other, stand up as far as they could reach, and bump chests. Is this an early attempt at sparring? These are supposed to be girls...do girls do that? They never hurt each other, it seemed more like they were testing their boundaries. You know how kids are.
