Hey buddy what's up? I have some bad news for you = ( it seems that someone is spreading another Jolly different than ours which has an English name I have seen it couple of times and whenever I asked for the one who brought it here people keep telling me that they do not remember the person who gave them this damn Rayquaza =\
No hatching shiny can only take place by two means :-
1- The one who took the egg himself/herself
Pokecheck is truely still in its beta version when it comes to legality analysis. Either way those eggs should be marked as Legal and there is no such thing as unhatched eggs too ..
Sure because they should have a valid location of hatching. And All of them have English names and OTs this means those eggs were originally brought unhatched and they were edited to change OTs , Names , and last but not least Being Shiny
