I have a Columbian Cross Rooster, beautiful and good protector of his 9 hens, but he also attacks people in the yard. Been reading through this thread and lots of good advice, but I have to agree, it does not good to keep a nasty rooster. Their memory is only about one day long so any lesson...
You do not want a Rhode Island Red Rooster!!! This year I got Columbian Cross hens and ordered one rooster...I ended up with two. They are magnificent birds, and were supposed to be docile...the hens are wonderful, the roosters become agressive. However, I have learned that they are NOT "mean"...
