What are the chances of all the Chanceys?


I left the country for 10 days and when i came back my local gyms were taken over by an unusual amount of Chanseys. The max I have seen in ONE gym is 7. Did I miss something?


I’ve only ever caught 6 Chansey and that’s WITH the Valentines Day event. I’ve never hatched one and I had to walk my Chansey a couple hundred km to evolve into my Blissey… so I’m missing something too apparently lol


Just have a bit more patience Niantic is working on solving this.
