Most Pokémon build nests, and Blaziken are no exception. However, their nests tend to be pretty sloppy affairs made from loose plant material. Since they really only need to hold the eggs (Torchic are up and active within moments of hatching), they really don’t need to be as elaborate as, say, a Chespin’s nest (Chespin nest in trees and the little ones are born blind and deaf; it takes about six weeks before they’re ready to move out of the nest for a bit).
