I recently ordered some game roosters from ideal poultry i ordered 2 black sumatras roosters, 1 red shoulder yokohama rooster and 1 black breasted red cubalaya rooster. I they sent me a lot of extras and they are about 2 months and a half old, and i cannot tell them apart. I already know that the black ones are the black sumatras. lol.
Here are the pictures see if you can tell them apart.
