My chickens are 4 weeks old and I have a good feeling about a few of them but not 100% sure. Rhode Island Red. Leaning toward hen. Barred Rock #1. We have two of these rascals and they look the same. Not sure on their genders. Barred Rock #2. Splash Cochin. This one I'm leaning towards hen. Or maybe that's wishful thinking. Lol Black Copper Maran. Really hoping for this one to be a hen as well. But again, I have no idea. Buff Orpington. I'm about 99% sure he's a roo. Buff Orpington #2. Leaning towards hen. I know that it might be a hair too early to truly tell but let me know what you think!
