Okay my 10 silver laced Wyandotte hens are approx 3 months old (depending how old they were when I got them at bomgaars I picked them up the day their shipment came in). They all look the same and act the same (like hens) would I know by now if one was a rooster? I don't think I bought sexed ones pretty sure it was a straight run batch but I didn't think I'd get so lucky to get 10 hens out of the deal.
