Not sure what day my fertile eggs are in

[dee06]

Hi hoping someone maybe able to give an idea as to what day my fertile eggs are on, they are under 2 tiny broody hens who had been missing for a few days before I found sitting some eggs, I bought them indoors as they were wet and on the ground, that was 2 weeks ago, I just candled a couple of them and they were very full with a large air sac, I can them moving.

Your best bet is to go to Hatching 101, and get some comparison pictures of eggs being candled at different dates.
