We recently bought 2 ameraucana chicks and they're about 4 weeks old. One seems very passive and more hen-like. The other is more aggressive and "wilder". It's illegal for us to have a rooster where we live, so we would like to know what signs we can look out for. What are tell-tall rooster signs in ameraucanas? These aren't our first chickens, but our first ameraucanas. Thank you!
