how old will my chicks be before the roosters start crowing? Mine are 5 weeks right now and im pretty sure they are all pullets, so i want to get a rooster, but i wouldent want to end up with 2 roosters and only 6 pullets. How old should they be when they go outside for good? Mine have all there feathers are 5 weeks old like i said before and are comfortable being outside for long periods of time. Are they ok to start living outside?
