Hello! I have 3 Wyandotte chicks and 3 Ameracauna chicks. They are 1 week old. I am curious, from your previous experiences, have there been any early gender indicators that you have noticed in these breeds. If I have read correctly they cannot be feather sexed, but do pullets feather out faster than roos? When do combs start to change color? Just curious to hear what you backyard chicken experts have to say on this?
