Can you determine the gender of a Guinea chick?

I just got 3, 1 week old guineas and I love them. But I do not know the gender of the 3. I have looked everywhere and I cannot find anything on sexing them at this age.

I know nothing about them, but if you haven't already I advise posting in the guinea forum, here: https://www.backyardchickens.com/forums/guinea-fowl.45/

Pretty sure you have to wait to voice sex them
