Newborn cockatiel crop not emptying right

Sorry for the blurry picture he wont sit still.

This baby is a day old by the way. After the baby hatched dad attacked it causing it to bleed and I assume the purple on the crop since that wasnt there before. Dad has now been separated In the picture it's been 4 hours since I fed the baby mom could of fed it but she hasn't been feeding it so that would be unusual. It is quite cold in my house trying to warm it up. He also just took a big old poop on my hand so maybe I just over fed him?
