"Do Trading Evolutions Trigger With First Stage Evolutions?"

#PokemonGO: Not sure if this has been answered elsewhere. But if someone trades a first stage evolution, (e.g. a Timburr) and then that person evolves it to its second stage (e.g. Girdurr), will it be a free third stage evolution (e.g. to Conkeldurr)? Or instead must the trade occur at the second stage evolution?I want to know so that I can instead attempt to lucky trade, the much more economical, Timburrs. via /r/TheSilphRoad https://ift.tt/384Ehyq
