About a year and a half ago I ordered 25 chicks from Cackle Hatchery, 23 hens and 3 Rhode Island Red roosters. A few months after we had some predator come in and kill 7 of my beloved birds that included 2 of my roosters. Ever since that event my one rooster has been very aggressive. He attacks whenever he gets the chance. He used to be so nice but now he's a ... ( well the nice way of saying it) a JERK! He's lucky he isn't on the dinner table right now.... My questions is why has he turned so aggressive?
