If the snake absorbed its yoke you are in no danger of it dying right now. They can live up to four months of the yoke alone. Yes he needs to eat before four months but give him some time to eat on his own. There have been lots of small babies that make it, even as small as 25g. It will do fine and eventually catch up. If it doesnt eat within a couple of months try force feeding. I would wait till he is showing signs of being skinny/dehydration before force feeding. Try fuzzy mice to start with this guy and if he takes it move up to hoppers. I sometimes wait two weeks after the 10day shed to even offer food to hatchlings. This lets the snake gert hungry and I rarely have hatchling balls not eat. Dont worry yet.
