These ladies?? are about 11 weeks old. My daughter's 2nd grade class hatched them so they were just straight run. I still think they are hens and I swear I stare at them for hours everyday trying to figure out what they are. Every once in awhile, one will make a sound that almost sounds like an attempt at a crow. I've caught the smaller one doing it. But I still believe they are pullets. We can't have roosters here in town so I'm just hoping we don't have to rehome them and order new pullets. I'm not seeing curling tail feathers or pointy saddle and neck feathers but it could be too early also.
