Can anyone tell me if this is a Roo? I have 3 buff orpingtons total and 4 barred rock. "she" is distinctly different than the others.. Her comb is much larger than the rest. Also has a darker coloring on top of head. And I just noticed red little wattles underneath the beak and none of the other chicks have this yet. Also she's been picking fights with the others and is atleast on the top of the pecking order, if she's not a roo.
2nd question, if it is a Roo, do I need to seperate them or can a Roo stay in coop with hens? (First time chick owner)
Thanks for your help!
