From the 25th of December 2016, there will be an increased chance to hatch baby Pokemon. So, I’m using up all my incubators to hatch all my eggs before Christmas. On Christmas day, I’ll visit lots of Poke Stops to stick up on eggs and burn through them with my left over incubators.
I’m so glad I was stockpiling incubators and coins. I figured that if need them for either a new year’s event or a January Poke Shop sale, but now seems like an appropriate time to use them.
