I got 3 barred rocks all at the same time. They can't be more than a day apart if not from the same brood. The one is definitely a female - darker and black legs. The other 2 I thought for sure we're males: white dot on head and predominately white. But of the 2 males, one has a definitely crown while the other is barely there and pale. I'm sure it's a male based on color but curious why one is so defined while the other isn't. Can someone provide input?
