if he seems weak and not eating on his own you could try some baby parrot formula and pedialyte, it can help jump start the little guys, i have used it for 2 dragons and it worked very well. You can get Kaytee handfeeding formula at your local petco and the pedialyte at the market, just mix it as directed substituting the water for the pedialyte. But like asked be sure to check your temps ect (105-115 basking / 85 ambient cool side temps). If you do feed this formula i suggest little but often especially to start out, you can use an eyedropper or syringe (without the needle) or if you have nothing else they usually will lap it off a spoon, they really like it (my 7 year old cockatoo still loves to be handfed the stuff )I hope this helps a bit, bare in mind also that some do not start eating till a few days to a week after hatching as they are still absorbing the rest of what food they received in the egg,the yolk sustains them for awhile after hatching, but if he looks weak and is on the small side the formula is a good idea.
