I have 7 completely mut chicks from a chicken farm far away from my house - (someone gave me the eggs and my broody hatched them) and they are cute but don't look anything like the pure breed chicks I had last year - so I have no idea what to expect with these cuties. What should I look for to determine there sexes? Are there universal generic signs that a chick might be a male or female? Besides the eventual crowing? More red combs, different types of feathers? I'm new to chickens and only bought sex pullet chicks last year.
