I am raising a few juveniles at the moment and have just got about 100 more eggs.
http://axolotl.org/rearing.htm will tell you everything you need to know about rearing, that´s a caudata site.
I got brine shrimp eggs from four season´s pet shop. $14 for 6g! Most pet stores sell them. They come with all the instructions. If you have alot of eggs you´ll probably want to cull some of them. From what I hear they can be really expensive to raise. Daphnia are a good idea for when they´re big enough to eat them http://www.caudata.org/daphnia/
