Yes, I think I was pretty lucky, although I had a fantastic ratio of managing to pick up mostly 10k eggs. I think I hatched around 70 eggs last week using multiple incubators from the last of the free coins I had accumulated over weeks and weeks.

Good luck with the regionals! I'm not too worried as I got all the regionals last time they came from eggs but my current status is four Kangaskhan and one Mr Mime, with the rest being the non-regionals which is somewhat annoying.
