Can you make an omlette with extra yolks?

[Katymac]

I've been making pavlova & DH & DD fancy omlettes for tea - I can bung an extra 5 yolks into a 4 egg omlette can't I?

Should I ask a bit of extra milk in to balance it or will it be fine?

Yep - it will just be a little richer

Thank you - they will be pleased
