Just tried a Zapdos raid a few hours ago. In a group on Discord for my community and a Zapdos spawned at the church not even two houses down from me. We got a group of 7 and took out a 42k Zapdos. Beat it with seconds to spare. Only one of us caught it (and he caught it on his first ball). Sadly I didn't catch it. Haven't even caught one legendary yet.
