No idea... I know it takes 55 days or something like that for them to hatch. Ask in the Emu group.. I'm sure someone can tell you. Ask your neighbor if they will take them back after they hatch
Also, ask if I can pick a few up on Feb 17th when I come over to Lego Land. LOL (you're close to that right?)
No, no, emus! You need d'uccle! I'm not far from LegoLand!
