Interesting. Seems like it can vary a lot! Maybe I'll get lucky and one of them won't crow at all so I can keep one. :fl what are the chances of that lol
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...
