How do you take care of breed leftovers?

[DarkMoonsDream]

I only started intensive breeding this generation. Just for fun trying to get some mons with good IVs and a fitting nature. Most of my breeding leftovers are located in a box, but I also wonder traded some. I like my Froakies. Many of them have 3 or 4 perfect IVs. Some even have Protean. But not a fitting nature. Much work to do still. If someone wants to have one and is willing to give me a pokemon that can be viewed as more or less equivalent, I'm willing to trade. If not they'll land in wonder trade someday. Or on the GTS. What I don't like to do is setting them free. I just care too much about them, I think.
