Actually it's 87.5% male and 12.5% female. Same goes for Snorlax, Eevee, Togepi, Combee, Lucario, all the fossils, and for some reason, Relicanth.
I think there's something of a taboo on Chikorita just because how popular Cyndaquil is. Heck, in all the other games, Fire is weak to the first gym (sometimes the first two) yet Fire-type starters are on average the most popular starters. Most people like Charizard best. Grass-types aren't really very popular. Well, anyway, I like a challenge, and I like to catch other Pokémon to help me, so...yeah.
And yes, I do know what I want my team to be. I posted it in that thread about potential lineups for HG/SS.
