By 18 weeks, shouldn't I be able to tell a roo from a hen? Seriously, I must be a freak. I'm planning to thin my flock a bit and need to rehome a few EEs. But I want to make sure that what I am giving away are indeed hens and not roos (I would hate to give someone a "hen" than starts to crow). Will someone please reassure me? Thanks. Also, I'm including a 19wk old Partridge Rock. She's a girl, too, right? No one is crowing and no one is laying eggs yet... Cupcake Leader Greywing Nugget Anonymous And the PR "Jane". She's about 19 weeks. Thank you.
