I responded to an ad by a member on another site for a free rooster that has been hand raised and needs a good home. They told me it's a Speckled Sussex. I picked up and brought it home and wow it's tiny. They said it's ten weeks old and it fits easily in the palms of both hands. he seems perfectly healthy, and exactly what they said he is, except I am concerned about the size. Is it possible he is a dwarf or something? Can a bird this small bred standard breed chickens? Or is it some sort of bantam Sussex and is just a small breed? He is fully feathered and has age-appropriate development as far as I can tell (I have raised about 30 or 40 birds so guessing). I just can't get over how little he is and if he will ever be accepted into the pecking order with the hens and ducks.
