I don't know what kind of roosters the person with 30 nice ones has but we have not had that kind of luck. I had 11 roosters last year and they drove me nuts going after each other. I finally had to separate them all till I could get them to freezer camp. If they got out they terrorized the hens. I have 2 now, my EE is a sweet heart but my Sussex goes after the kids, and has gone after me a time or three. I carry him, net him, and box him. Have to keep my eye on him all the time.....I am not enamored by roosters
Good luck with your birds. Hens and some roosters are great!
