The chick does have a tail (parsons nose) but this is coming out of the back just up from that. I wet the area to see how it looks this morning so it's wet looking because I wet it for photo's and to see if it was still there under the fluff. I put it back in the incubator alone to fluff up again and dry so the other chicks didn't notice it and start pecking at it. It's not noticeable in the fluff

What do you make of this?
