Does this mixed rooster have the short legged gene?
He does appear to have unusually short legs, but I can't really tell from that picture if he does have the creeper (short-legged) gene. Do you have any idea of what breed/mix he is? If he is part Japanese bantam or Dorking, he might.
Edited to add: I just saw your other post about short legged genetics where you said you have a rooster who is 1/4 Japanese, 1/4 Silkie, and 1/2 Jersey Giant. If this is the same bird you are talking about there, then, yes, he does have the creeper gene.

Have you tried the Chicken Calculator? According to it, a rose combed feather-footed short-legged chicken is a possible result of a Japanese (creeper/short-legged gene) x Silkie (crested, feather-footed, silky-feathered) crossed with a Jersey Giant (single comb). I have found it to be accurate, so maybe you can predict what you'll be hatching when you cross him with the Wyandotte and Game hens. That sounds like it could result in some cool looking chickens
Hmm, yeah, I didn't consider that. Maybe it isn't Jersey Giant after all? Or could it be white Jersey Giant? That would work if the Jersey Giant was recessive white depending on the color of the Silkie (assuming the Japanese is black-tailed white). Is there any way to contact the person you got him from to ask?
