I have 8 hens about a year old and about 28 chicks about 8 weeks old mixed in with the older hens and free ranging. I know someone who has a rooster and 4 hens for sale for 10 bucks I am wondering how introducing a rooster with the chicks will go will I have to worry about him attacking the chicks or will he been to Bush with the hens. 2 of the chicks are roosters will that matter as they grow?
