Okay, thanks. I have fifteen hens total if my gender assumptions are correct. Here are pics from two weeks ago.They will start crowing usually around 10-17 weeks. Probably not if they were raised together. If you post pictures we can help you identify them too if you’re not sure. If you can have roosters in your area tho and you are planning on keeping them, make sure you have at least a 5-1 hen rooster ratio.
