I have a 5wk old chick that is a RIR roo / (poorly breed) EE cross. I was sittin in the outdoor brooder just chillin and I notices this one chick had no tail. I checked her for on injury and what I suspected as feather plucking. Found nothing..... Where the tail should have been there's an ever so small pad of skin. Other than that she is healty and on the same devlopmental level as the 10 other chicks. Is there a breed that does not have a tail???
