I caught two of each legendary egg (except Kanto and Johto, since I couldn't find any). My two Hoenn eggs were both Rayquazas, in which one was already ready to hatch. My two mythical eggs were both Mews.
I have 12 moltres eggs. 12. I was a little too enthusiastic to catch 'em all when they first appeared...
I think I have two each of Palkia, Dialga, and Deoxys...that last one is a guess, honestly, I'm not positive.
I got confused when the Kanto eggs first changed and thought they were new, so now I have 2 Mew eggs lol.
Two Mew Eggs, and I have a Ho-oh egg after already capturing one, and a Lugia Egg after already hatching one... Not to mention a Celebi Egg, after already hatching one as well. @_@
I'm sure we'll get trading eventually, and I'm sure that the Valor team is working hard on bringing trading to LV. Coding something like a trade system can be pretty difficult (especially making it bug free!)
I was relieved to find I don't have any duplicates! I was always pretty careful to check whether I already had an egg in my collection before catching it. Was worried I'd have duplicates of gen 1, because I hadn't noticed that feature yet, but I got lucky. The only one I've got left is Articuno, which I hadn't hatched from another egg yet.
I have two mews now since I didn't know that the egg was going to be a mew, but when trading becomes a thing, I guess I'll have the upper hand in that.
