Is this a sign of a roo? Our black chick started charging at the other chick this week and pecking it a bit. The speckled chick will stand his/her ground and peck back a little, but doens't seem as aggressive. Today I saw the black chick get kinda confrontational to the other chick and stand up and raise it's wings. The speckled chick did the same back. Is it just roos that do this stuff?
