Hello, I am new to backyard chickens. I have a mixed flock of 4 week old white crested Polish, silver laced Polish, Easter Eggers, buff Orpington and Silkies. Some of my Polish are starting to appear different than the others in that their tails are longer and straighter. I'm trying to determine if these are the hens or roos. Any knowledge y'all are willing to impart is appreciated. The first photo is the one I'm guessing is a hen, second photo roo?? (Longer tail feathers). The last photos are of my only silver laced polish. Hoping for a hen, but I'm stumped. It's super calm and sweet. and loves being held.
