When you say curved pointed tails are you talking about the dark one at the top or the light colored chick who only has a fluff but so far is curved down with the body? Here are the two crests. The legs didn't look enough different for me to tell anything.Curved, pointy tails indicated male on mine. My pullets tails stick up like an adult hen does. Compare leg thickness with each other. Males have slightly thicker legs than females.
