I processed the two roosters out of my 6 cornish. They are 12 weeks and 1 day old. I tried the pithing method, then cut the jugular right after... however after they were pithed they were very much still alive and I thought since it was going through the brain it was supposed to be instant death? Did I do something wrong? On a good note; My biggest roo gave me a FOUR POUND BREAST!!!!
