Hi, new to this cockerel thing. I hatched my own chicks and currently have 12, some are showing signs of being cockerels but they are only 10 weeks so I am not sure how to tell. They all seem to be getting on very well at the moment, are you saying that I will know for certain when they are 4-6 months ? I want to keep one, my neighbour wants one and I would like to rehome the others if I can because I'm a softy. Any help with how to sex them would be helpful and at what age I am likely to start getting problems. Thanks
