Whose the father of the egg?

[gamefowl-layers]

Exactly 8 days ago, my Gilmore Hatch hen crossed over to the other pen and my other Frost Grey rooster mounted her (we are improving the bird cages so she got away). Today, that Gilmore Hen went broody and her last egg laid was yesterday. Will the father of that egg be the Gilmore Hatch Rooster or the Frost Grey rooster? Do you think it's a cross-breed egg? Thanks for any help!

Since hens can retain sperm with high viability for longer than two weeks it is possible that either rooster might be the sire of any chick to hatch from eggs laid after her 'romance'.
