How to feed my shedding milk snake?

[Condog]

I feed all my snakes in their enclosures whether they are in shed or not , it applies to BP, Milksnakes, Bulls, Carpets and Blood

I read everywhere that i should take it out to feed it. That way, it will notice that every time it's in its "hunting area" it knows its time to eat. Because then if you feed it in the enclosure it wont be able to tell if you are just trying to handle it or give it food. Also, the snake could ingest some substrate with it's meal, not good.
