Still don't know about these guys... they are four weeks old, and I only know the breed of one of them D:. Help me out? They are all bantams. This is Jenkinson, a buff brahma bantam. I'm thinking it MIGHT be a roo, but am not sure. Burke (black) and Harman (white), I'm thinking they are roos, and almost certain Harman is. Harman seems very heavyset, whereas Burke is slimmer. Both have single combs. Harman again. Burke again. Chicklet is one of the smaller chicks. I'm guessing pullet. Schultz is also very small. Again, thinking pullet.
