Hello, I introduced myself on the New Member forum this morning. I'm new to chicken ownership, despite my years-long adoration for them. Last week we picked up three 13 week-old chickens (two Ameraucanas and one GLW). We're hoping for pullets, but we're not sure if they're all hens. I don't notice anything obvious to distinguish. I realize these aren't the best photos, but maybe someone with experience has an idea?
