I jhave a newly hatched chick trailing some goop. I assume it's yolk sac and umbilical cord I see. I suspect it was born a bit before it was ready- another chick actually managed to smash part of its shell opposite to its pip. There's a bit of a pink skin protrusion and then this goop, which is more greenish brown than yellow. Is it a goner? Is it a waiting game? Can I help? It's walking around some. It hatched maybe 20 minutes ago.
