Help! This has been a difficult journey with a confirmed 6 out of 8 chicks male and now the final two have started crowing - one yesterday and the other today. They are 10 week old bantam crosses. Does this definitely mean 8 out 8 are cockerels?? Am I the most unlucky first time egg farmer ever?? The last two look very different to the other 6 with much smaller, paler combs and generally smaller chickens. No saddle feathers in these two yet. Is the crowing conclusive at this age?
