Is it possible to spay a bird pokemon? I have a female pidgey who has become close friends with a wild taillow who keeps coming into our backyard who happens to be male. I’d like to keep their friendship going but I’m not sure if I’d be prepared to take care of any eggs or hatchlings they might have. If it isnt possible, do I just need to supervise them all the time?

While it’s possible to spay a bird pokémon, it’s extremely difficult and could lead to complications that, in short, means it’s not worth trying unless the pokémon’s life is somehow jeopardized by being intact. That having been said, I’m afraid that’s about all you can do, anonymous, other than training your pidgey to ward off unwanted advances on her own and to avoid mating if at all possible. The only other suggestion I can make for this is to look into options for rehoming eggs in a humane manner, just in case.
