Tell if a supposed hen turns out to be a rooster? I purchased a dozen chicks from a reputable dealer here in Texas. She guaranteed they were all hens or she's replace them. One of my Americauna girls is big. I mean MUCH larger than all my other birds. 2 Amer 2 Australorp 2 Buff Os 2 GLW 2 Golden Comet 2 Barred Rock I'm comparing size of her body and feet! They're massive! Any help on how early I can tell. She's definitely highest on pecking order. Runs the roost to say the lease.
