Tonights 9 10K batch hatch results :(
Out of tonights batch hatch the only good thing received was mareep. Yes, the sheep that seems to always be very elusive to me even though I'm in a water/electric biome. I literary yelled out when that sheep popped out of the egg. The Lapris and dratini candy were not bad either but lapris is common due to the event and dratini is always common to me.
For those trainers that batch hatch 9 10K eggs, are your RNG results similar where 2 or 3 eggs give something good and the rest are just duplicate fillers like Mantine, Gligar and Pineco?

I usually batch whichever 10k eggs I can collect in a 2 week stretch, to correspond with my 7 day streak lucky egg and mass evolve, sometimes 9 or 8. The 1/4 to 1/3 good hatch rate is about what I hope for. Today, I only had 6 10k eggs collected (the drop rate for 10 k has been slower for the past 2 weeks for me). This batch was really disappointing, as I got only 1 Dratini, then 2 Sudowoodo, 2 Mantine, and 1 Gligar, so 5/6 crap. RNG was not kind. Oddly, since Gen 2 I've only hatched 1 Mareep (my walking buddy) and I've still never seen or hatched a single Militank. Amphoros, Militank, and Unown remain the only non regionals needed to complete my dex.
I just hatched 8:
Dratini
Mantine
Sudowoodo
2 Larvitar
3 Pineco
3/8 not bad. however unfortunately the highest is one Larvitar at just 86%. In happy with the candy for all of them - even the pineco. I held on to that one Larvitar in case I feel like walking him. The rest were sent to the prof. A few bad(expected) hatches could damper my spirits after today!
That being said how much candy do you get for a 10k? My Larvitar count is only mid thirties. I had 2. So roughly 16 candy per egg?! Why did I think it was up to 30...
