Same here on Chansey except I have hatched one.
When the new ones were released I came across a Blissey straight away. Not having a clue it was special I let it get away. How long will I regret that!!!
Easiest thing is to use the appraisal feature and look for "Wonders". If you want to know exact stats you will need to find a calculator- it is based on how much the CP goes up when you power the poke up.
I don't see the need for precise stats. All wonders are good enough and you won't have so...
Based on the screen shot of your pokedex and the Halloween event I'd be making a Dratini your buddy. I don't think you will be short of Bulbasaurs post the Christmas event.
And I did get a incubator this morning!
Finished today! Got everything except for two of the regionals.
It took 11 weeks. But I got everything except for five in the first six weeks. (I work in a VERY poke-rich part of the world). The next one took a week but the last four have all been in the last four days since the Halloween...
