I have what appears to be 3 roos and maybe even a 4th from my 9 chicks. They are all in a brooder with what I assume is plenty of space until they can be moved outside. When the 'maybe' roos are just jumping and tumbling and beating on each other... and beating the potential pullets too. Isn't it a bit early for them to worried about who's in charge when they still sleep in a heap in the corner? Or, is it a male thing, and they are really are just being rambunctous boys?
