Aggression is a very real possibility, sadly, and something those who keep them must be prepared for. However, this isn't always the case. Some of my very best, most affectionate birds are roosters.Just that I heard that they are more aggressive and we are so new to the Chicken World! Can you have a Rooster in with your girls if you do not wish to raise baby chicks?

Of course! Simply don't allow the girls to incubate eggs, if possible.
