Oh, I miss dyeing eggs, I've not seen any kits here for that. We always used to dye eggs when I was a kid.
We also have one very very cool easter tradition - no egg hunt, strings instead. The Easter bunny comes into the house and lays strings, one per child, in "their" colours, with goodies on them, and a nice big goodie at the end. Not a lot of chocolate, often a book or whatever.
This is fairer for kids of different ages (which is why my parents made it up). Also, when kids are bigger, you get the kids to lay out each other's strings, and the grown-ups just put the goodies on them. The strings can be quite evil, with lots of going under around and through things.
(Like my mum, I get in quite a huff about that horrible Easter bunny and his horrible strings messing up my house.)
