WHITE: White Chihuahuas are almost totally devoid of black pigment. This is not the same as what is seen in parti-colors. Solid whites usually have pale noses and eye rings, and somewhat lighter eyes, almost albino in appearance, but not quite. This is very rare in chihuahuas, usually because it would take two white doges to make white pups with this effect.
Cord care is how to care for your baby's umbilical cord stump. Before your baby is born, the umbilical cord brings nutrition and oxygen to him and removes his waste. After birth, your baby does not need the umbilical cord anymore. Healthcare providers cut off all but a small part (stump) of the umbilical cord. The stump dries and falls off in about 7 to 21 days, leaving a bellybutton.
Anyways....just leave it alone, it's perfectly normal, all chicks have a little umbelical cord when they hatch. By the time he is fluffy, the cord will have dried and fell off. Only worry when you have a chick with it's organs falling out of its belly button, this has happened to me plenty of times. If you think you have a chick like that, then post some pics or describe how it looks so we can help.
