What have you been hatching lately?
For me:
10 km - Last four were Chansey (a 96%!!), Feebas (my first wonder), Mareep (meh) and Trapinch (finally enough candies for a Flygon).
5 km - Mostly so i herd u like mudkipz and Torchic, interrupted by a Wingull and...a purple Wynaut!
2 km - Last three were Machop, Togepi and Spheal.
Bonus question: Is there an updated hatch probability list?

All community days aside from the starters (yes, Pikachu's a starter) have been 10k egg pokemon with three stages, and only 3 pokemon fit that criteria that arent the pseudo legendaries of gen 3, those being bagon and beldum.
that leaves just trapinch ralts, and slakoth. we can chop slakoth off that because that is highly unlikely to be a community day because whe whole POINT of it having yawn it so nerf it and giving it a decent fast move would break it, so we have 2 pokemon, and seeing as theres likely going to be 2 psudolegendary CD's one for beldum and bagon, there may be 2 other pokemon having community days, those being ralts and trapinch.
Flygon, I have no idea what they could give it, maybe some thing to make it better and not just am off brand garchomp, and for gardevoir possibly the first fairy fast move.
the possibility may be slim, but I know people who powered up and evolved about 3 100% larvitar because they thought there would never be a tyranitar CD, and now they all regret it
Evolving a potential CD pokemon, in this case flygon, when that pokemon has almost no viability right now doesn't seem worth the risk, mostly because flygon is completely useless right now, theres not really any benefit from evolving now as opposed to seeing if they do a CD for it in a few months when it could be made a lot better
2 and 5k: I don't keep track really since almost all of it is trash. Got a Togepi recently and I think a Wynaut two weeks ago, that's about it. There are lots of starters for sure.
10k is giving pretty much everything evenly to me. 2 Chansey, 2 Feebas, 2 Beldum, a few Larvitar and Dratini, a few Mareep and Trapinch from what I can recall of the recent hatches.
I saw someone working on a new list at TSR but don't know if they got enough data for it.
Finally someone who actually knows how to use the plural of pokemon names on this site.
I agree with the 2 and 5 k's being trash, togepi's going to get better when gen Iv comes, but as of now, most of them arent really worth the time to hatch, which sucks because they take up so much room in egg inventory (probably the dev's way of preventing players from getting the actually good pokemon they want)
