A couple months ago i intentially ordered a rooster at the feed store. When he came in there were all different kinds of "chickens" with him, so i bought 6 of them to go with him because l didn't want him to be alone. Him and 2 others grew really fast so i let them out with my older ones. Of the 4 remaining, they are not acting like hens. I know for sure that one of them is a rooster because he "cocka-doodle-doo's" and protects the others altough he still is very little. The others aren't protective but they freeze and stare at the other roosters and their feathers pop out at their neck. Does this mean they are roosters too?
