okay now i need advice. i have 3 roosters in a pen with my meaties. i was fattening them up for slaughter. here is the problem. the 2 columbian marked ones beat the heck out of production red rooster. the 2 ganged up on him started to peck him to death.i removed my not so manly rooster. it did not look like a pecking order problem. so i am not sure how to treat the other 2.
