I have two Polish chickens and they both look to be roosters, but today I noticed the smaller one clucking like a hen and going into the nesting box and sitting. So now I'm wondering if I have a pair. The one that I am 100% of being a rooster has these red devil horn looking things sticking up on each side of his beak. His tail feathers are two rows and are open in the center (from the back) and come up to a point at the top. The one I suspect to be a hen has two rows of feathers that are in a row together, not open. This one also is a blue or lavender color while the bigger one is various colors with prettier markings and splashes of color on his body.
Is there any 100% sure way to tell which is which? I can get some photos of them, but I'd need to know exactly what to photograph of them. Thanks! -Rachel
