I have at least two confirmed cockerel in my flock so far, despite buying from the pullet bins. Such is life. I am not allowed to have roosters per my city ordinance, so I will need to rehome them at some point. That point will probably be when they begin crowing. My oldest is a close to 10 week old SLW. Not a peep from him so far. The youngest is a 4 week old barred rock. Right now they are outside together but separated by wire because I'm integrating the second part of my flock to the older ones.
