When the event started , i had only 5 ks . Had 9 incubators running for the first time , most of these eggs hatched simultaneously , then in came a flood of 2 ks with two 10 ks as well . As i didn ' t want to blow incubators on 2 ks , i always had 79 eggs and immediately , i was back to getting only 5 ks again . Recently , i did very little walking after finally getting to hold 10 stable gyms . So once more , i had a lot of incubators running at the same time and as soon as i cleared up some egg space instead of having one or two free slots at most , in came a wave of 2 ks with the token 10 k mixed in . Now that most of these incubators are spent and i ' m back to one or two free slots at most , it ' s all 5 k again . Of course , that could just be coincidence . With so much in this game being RNG , it ' s more than likely it is . But it would be a big deal if it was confirmed , and would give me some rest if it was falsified . Just as that impression i can ' t shake that some stops give out eggs of certain species . All of my onix eggs came from the same stop , both of the 10 k eggs i got from another one turned out to be Electabuzz , both of the 10 ks from yet another hatched the only Scythers i haven ' t caught in the wild , both of my Snorlax hatched from eggs found in the same area and the only Pinsir , only Hitmonchan and only Aerodactyl i ' ve ever got are all from stops i have never gotten a 10 k from before or after . I haven ' t hatched that many 10 ks only at 246 eggs total , so i ' ve got a good overview of this and the only 10 k eggs i cannot trace back to their stop are one Eevee , one Jynx and one Dratini . Really , really looking forward to that study to know if i should go for future mass hatches and then keep spinning the same stop for a 10 k or if i don ' t have to bother avoiding cursed egg stops anymore .
