Ive had a bunch of roos before. The first year we had chickens we bought 20 chicks from a livestock store. 10 black australorps, and 10 rirs we ended up with 5 australorp roos, 5 australorp hens, one rir roo, and 9 hens. We kept only the rir roo, and the hens. The next year, I hatched one chick from him wich also turned out to be a roo, who turned to aggressive, along with his dad. We got rid of the flock and sent them to another farm because they developed issues we couldnt handle at the time, then last year we got our current chickens, and thankfully only ended up with one roo. The chickes are australorps, and ees. Our roo is an ee. Last year, toward the end of the year, we hatched out another chick, wich did turn out to be a roo, sadly. This roo was friendly like his dad, at first, so he was allowed to roam once he was big enough. But at some point he developed a mean streak, and pushed the line when he started chasing my toddler twin brothers around the yard so he became lunch. However, his father is excellent. All the time we've had him, he has never shown any sort of aggression
His father is named big red because hes big and red, he was called chirpy because he was so loud at night that we could hear him from our bedroom up stairs as a chirpy chick. And he'd chirp and chirp, and chirp, until surrogate mom (me) came down to hold him in wich case he would usually fall asleep on my chest. Now he has a younger sister that he'll never meet, called baby.
