Hi KLIL and everyone. I'm sure you know this by now, but lil' Light Sussex is all boy! lol He's a beauty & should grow up to be a gorgeous rooster! I hope your little Australorp guy learns to mind his manners for ya. I had 2 Australorp roos several years ago. Both were jack-@$$es - 1 was serious about it and the other was kinda stupid and mostly charged and ran into me without jumping up trying to spur. Neither one stayed after that behavior started.
I had an Ameraucana rooster (he was nuts when I got him as an adult) that was the meanest S.O.B. I ever saw. A farmer wanted him to free range on a big farm so he could be a great protector of a whole bunch of free range chickens. He got lucky is all I can say. HA!
