This is my first time raising backyard chickens and I have been looking up information on how to determine if they are all three hens. My Barred Rock and Gold-laced Wyandotte pretty clearly match the descriptions of hens, but I think my my 4 month old Rhode Island Red might be a rooster... I could use a second opinion! This photo is Roseanne at 2 months... And both of these photos are Roseanne at 4 months... Thanks for your help!
