Ok, so I think I may be jumping the gun thinking my profile pic is a roo (3 months old at picture time). I could swear I heard a cock a doodle out of this bird. But now at 4 1/2 months, he/she has short neck feathers and rounded tail feathers. I was going by the occasional light crow as my thinking it's a boy. But since it's a Barred Rock/Brahma mix- I have nothing else to compare to. When is a rooster definitely a rooster?! No aggressive tendencies either. Any thoughts here? I don't want to give away a perfectly good boy if she's actually a girl!
