A little more info:
A rooster flock is a flock that only consists of roosters. The roosters' pen should be big enough so all the roosters have places to hide/run from other roos, and it should not be in sight of the hens.
Introduce new roosters when they are about 3 months old, and watch to...
If you have too many roosters you could start a rooster flock (I started a thread called "Rooster Flocks" if you want more info).
If I lived in Ohio I would definitely get some! lol! Those are some pretty boys! :)
