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.
