I think the problem here is the join between the hand and the chicken-neck... it looks very awkward and because of the size of the hand i guess it's quite unbalanced anyway. You could have the chicken with it's neck pointing downwards (well, to the side) then you could have the wrist and hand coming out of it in a horizontal direction

, although there's still the problem of the chickens neck being so much smaller than the wrist should be and the hand would still need to be weightless. Or, you could put the hand at an angle, which would take away the awkwardness of it atm and perhaps fix the balance problem. When i put my thumb up i don't bother straightening it so my thumb is 90 degrees from the ground, i just hold it at the angle that's comfortable. So yeah, i'd rotate it a bit anti-clockwise, and you may want to make it smaller so the wrist and neck widths match.
Good luck, it's a weird yet wonderful idea.
