I like the kennels you use... i also bought some dog kennels for my stags.. Very heavy duty wire..Nothing wrong with performance breeding or breeding for your wanted traits. I used to be- and still am scared to meet a blue or off colored rooster. They seem to cut so good. I felt like if I could get past the first pitting I was ok.
My only off color breedings are some black fowl I have.
