Have you ever kept an adult shingleback? Which subspecies are you getting and where you are located? This information is required to fully answer your questions.
From birth, the young eat the same foods and require the same captive conditions as adults. The only difference is that their food needs to be diced a little smaller than what you can feed an adult. This includes their leafy greens, as they are not able to tear bite sized pieces off the plant as they would in the wild.
While shinglebacks are not difficult to keep, if you have not kept these skinks or other bluetongues before, then you cannot expect to someone on a forum to write out everything you need to know. However the following will provide that.
There are a number of excellent books on the subject. Some are now hard to come by. They can sometimes be picked up on places like Gumtree and Ebay. Also, your state library may have copies for loan:
· A guide to Australian Skinks in Captivity. By Danny Brown (2012 Reptile Publications, Burleigh).
· Keeping Shingleback Lizards. By Darren Green.
· Keeping and Breeding Australian Lizards Book. Edited by Mike Swan.

Whilst they are solitary in nature, you can keep more than one together as long as there is sufficient space provided.
