I'm starting to think the Jersey Giant I thought was a roo is actually a hen. He's 7 weeks old now and even though his comb is not small, it's very yellow still. I had three other roos who hatched the same day; barred and white rocks - and their combs were all very red. I know the JG grows more slowly, but I thought it would be more pink at this point at least. Thoughts from my fellow chicken folks?
