I think it could go either way about who the father is. It may be smarter to wait, unless it will be perfectly clear from the babies which father it is.
I tried that once only with a tremper albino male and a hypo. whatever male had beed breed to her first was the parent of the first clutch (albino) but the next clutch was the other male (hypo) so its really just the luck of the draw when it comes to that.
