For me EEs were always the hardest and took the longest to tell which were roos. But if I had a few of the same breed the differences showed up easier.I don't blame you. I hate it too. I keep looking at my girls and every day I think ones a roo, then the next day, not a roo...It's maddening.
I have one definite rooster, and now my other EE is beginning to look like one too. Ugh.
But single combs are much easier I think then rosecombs etc.
The gals stay pale pinkish/orangish longer and the roos definately turn pink then darker pink then red much faster.That and omnce you really study faces, hens have a softer more rounded look to me. Roos look more manly.
