I can't give Walt's reasoning. See, I was raised with these birds from day number one. Though at times in my life I didn't have chickens (college years) I've been with them all my life. I don't ever remember beginning. Thus, I'm not the one to help with this answer.
I said that they are not a beginners bird because they can be so aggressive toward other chickens. I don't have near the experience with these Orientals that Saladin has, but I have never seen 3-4 week old babies getting into lethal fights like these can. In some ways my females are even worse than the males. It takes some experience knowing who and how you can put these birds together in a confined space like a breeding pen. Most chickens will fight, but when these fight there is one dead at the end of it....sometimes both. They have to be bred responsibly to ensure that they are never mean towards humans. They take more work, but there are no chickens that are as noble as these ancient breeds.
