Pokemon Go Christmas Event is currently going on which was reported to grant several in-game bonuses to their players. One of which gives a free Egg Incubator for achieving the First Spin of the Day achievement. As previously reported, players will receive at most ten Egg Incubators during the whole duration of the event. While some are enjoying this free item, others are wondering if is there a limit of Incubators can they hold.
According to the report from Otakukart, the answers are still unclear unless someone tests it. This issue was posted on the Pokemon Go Reddit forum called The Silph Road. Based on the post, it seems like one trainer may have actually give it a shot. While other trainers have suggested that there might be a limit, some speculate that they can hold Incubators with the same number as the Eggs. This theory does make sense. However, it also possible that one player can hold as much Egg Incubators as he/she wants and the limit will just fall down on the trainer's bag space. Moreover, if you are expanding your bag's capacity, one question still remains regarding the limit of your bag size.
Meanwhile, it is still doubtful if Niantic will allow players to have their bags full of Incubators just to know if there is really a limit. Perhaps, it is possible that the company have not yet thought of players doing such things as there are obviously million reasons not to do it.
For those players who are really curious to find out regarding this current issue, they can try their luck discovering such. In addition, you can also check the forum The Silph Road to follow the progression regarding the Incubator limit topic. It is worth noting that it will take time for them to post an update so it is recommended to have patience.
