I've now also hatched a Pidgey (oh joy another Pidgey) and a Bellsprout (which I actually didn't have despite seeing it on the radar constantly, so that was nice). I kind of wish eggs had some sort of countdown independent of walking for those of us with less access to GPS, because I constantly have 9 eggs.
I have to agree with this because for me trying to walk anywhere for 10km eggs takes me ~ a week because the majority of the time I have to drive and normally I can't just get up and leave my house. Especially if this 10km egg hatches into an Eevee I'll probably be livid because of how long it takes and how dastardly common Eevee are here. They're great for powering up my Eevolutions, but I don't need to hatch them.
