How do you keep them, what have you been offering and how often?

24 days is nothing, they shed 10 days after hatching and usually you feed them their first meal 2 to 4 days after that so you are really not that behind.

Sometimes it take 4 to 6 weeks before they eat, the important is to know when to intervene and what need to be adjusted if there is the need to do so and for that you need to provide a little more details.
