How likely are my first eggs to be fertilized ?

My 5 girls are about 26 weeks and I'm starting to get some eggs. They have been with 5 roosters the same age the whole time. How likely are my first eggs to be fertilized ? How soon can I tell?

I have my 8 month olds first ever eggs in the incubator at the moment and i know the second one she laid is definitely fertile. I am candling the rest in 2 days to check for veins.

In terms of how soon can you tell. I would imagine as soon as you put them in the incubator for a few days to see if veins grow.

I wait until they lay their 4th egg. By then I can be sure
