My novel has a half-page prologue and I was wondering if that would be considered a chapter.

I was thinking about submitting during Firebrand Agency's query holiday where they're taking the first chapter instead of a query, but I don't want to just give them the prologue since that would be silly. I don't think the story works as well when I try to integrate the prologue into the first chapter. I might be able to cut it out all together, but I'll see. Also some agents/publishers ask for the first three chapters, but would that be the prologue and the first two chapters after that? Obviously, I shouldn't be considering querying if I haven't decided to include the prologue or not, but I'm just curious.
