So I'm new at raising chickens and I bought my chickens from Tractor Supply (didn't know any other place at the time). I was told all the chickens I bought were sexed and females. But the past two mornings I've heard crowing coming from the coop. One chicken in particular looks completely different from all other chickens. How can I tell if it is the rooster? I have attached pictures as it won't allow me to get closer for better pics
