hey it is me well i have a suggestion use the honey trees and every time you check a tree save before hand and when you encounter a combee just reset until you get a female one --- I am the Dragon King
What you do is honey up several trees. When you come back later to check them save the game before you actually check the tree. Find a tree with a Combee in it. If it's male soft rest the game and check the tree again. Repeat until you have a female. Stats of pokemon on honey trees aren't decided until you check the tree, this includes gender.
