Since hatching eggs is such a big part of progressing in Pokemon Go, and you only have one infinite use incubator... this means incubators are a pretty useful commodity. Can you ever receive them from Pokestops? And if so, what level do you need to be?
I don't believe that you can receive Lures, Incubators, Lucky Eggs, or Incense from Pokéstops, and that you must either purchase them from the store or receive them as a reward for leveling up. I don't have any evidence other than anecdotal at level 20 with 1000+ visited Pokéstops. If anyone has any counter-evidence please post it!
According to http://www.gamesradar.com/pokemon-go-level-rewards/
You get 1 incubator at level 6, 10, 15 and 2 incubators at level 20.
Items from the Shop (with the sole exception of Pokeballs) may not be acquired without the use of Pokecoins or the level-up bonus.
This is an intended feature of Niantic's -- these items are "premium," and therefore, are to be bought in order to generate a revenue supply from the game.
You can get incubators from pokestops. I received one (with three uses) a couple of days ago around level 4 or 5. Unfortunately, I didn't realize it was apparently a rare event or I would have taken a screenshot. It also has fallen off my journal or I'd screenshot that. They are out there!
The incubator is on its last use now so I was trying to check how rare they are from pokestops when I found this question.
Edit: I see now that you apparently get one from leveling up to 6. I was pretty sure I had it before then, but perhaps not. I don't have two, so if you 100% get one from leveling to 6 then it must be that one. Leaving this post for posterity anyway cause why not.
Yes, you can get incubators from Pokéstops. All the incubators I got were from Pokéstops. I didn't spend any money on them. I had a lot of luck I guess, because my brothers and cousin didn't get any of them.
Can't say for sure, but this page from "International Business Times" says you can obtain Incubators from Pokéstops.
soo a friend of mine have 3 incubators and she says that she got them frome pokestops and i belive here she is only lv 7 so yes i think u can get it frome pokestops but its has a low drop rate ^-^
