So I got 2 red stars about 8 weeks old from a farm. This morning, I swear I heard one of them crowing. After I've read some of the threads here, I think the farmer may have bred them over a couple years because she had a couple coops full of red stars. The one I think was crowing seems to have white tail feathers, but the rest is red. So is it pretty much a sure thing that if they crow that they are a rooster? Not a confused hen?
