Catching The starter Pokemon

Just want to get your view on this has anyone noticed how hard it is to catch the starter Pokemon and I mean the high cp ones from say 200+ they certainly drain my pokeball inventory its hard enough to find them why is that I’m living in Ireland can that be the case

Starter Pokemon have a relatively low base capture rate, 20% compared to an average of 40-50% for other common wild species.

Well I’ve nearly gone through 10 ultra balls to catch squirtle and chikorita I think that’s how it’s spelled lol and squirtle is only seen once in a blue moon around where I am lol
