MagiStream

I am trying to trade an egg to another new player whom is doing a quest.

When I start the trade I can not click on the egg, in fact, all of my eggs are not showing up.
How do I trade the eggs I get from the stream or at least, how do I make them show up to trade them?
I have the egg in my main keep and had it for a few days too.

Unfrozen eggs cannot be traded, so they won't show up.

Oh wow, I Didn't know that. Thank you for letting me know Mathcat!

Also, once frozen you can't unfreeze an egg, nor can frozen eggs be used as quest material(so freezing it and sending it over wouldn't work).
Your best would be to lend breeding materials to them so they can try to breed their own egg.
