I had gives my murhrow to hold the dusk stone after he level 41, now he is level 44, and he haven't evolve to honchkrow yet. Is there any step I need to do to trigger the evolving.
Don't hold it, but use it! Take back the item from him... Go to the bag, find Dusk ball, press "a", and select "use", after that choose the Murkrow, It will evolve to Honchkrow...
You don't give him a dusk stone to hold you go in your bag and find the dusk stone and pick use on murhrow.
You use it on him, not let him hold it. After that, he should evolve.
