Yes, they do, and I believe it is because of the hatchery reds. The big hatcheries, as I understand, breed large numbers of birds with goals toward volume and production but no regard for temperament or SOP. I had one of those hatchery RIR roosters a long time ago and he lived up to the reputation. Spurred me right on the ankle bone. It hurt so bad, I had to use a cane to limp along. My heritage RIRs (I have the Reese aka Mohawk line) are not like that at all. They will check me out when I go in the pens with them and their hens, but that is all. I can turn my back on them, no problems.Hey everyone....I found out a couple years ago that my great-grandfather bred RIR's in what is now Burien, WA for years. In the 50s, he shot a couple guys who were trying to steal some of his prize hens! LOL I must admit that I was hesitant to get reds because I'd heard the roosters had nasty temperaments.
