Suppose you have a Deligne Mumford stack which is a quotient $[X/G]$ of a scheme $X$ by an algebraic group $G$ .
What is the normalization of that? Is it true that its normalization is a quotient stack of the form $[X'/G]$ , where $X'\rightarrow X $ is the normalization map of $X$ ?(where $X$ is not necessarily reduced or irreducible)
Same question for $X$ an algebraic space.
