When should I take the nesting box out of the cage?

Hello, my buns are 19 days old today and the seem so confy in their box, I read somewhere that shouldn't be there by day 18 because it will increase the chance of nest eye. Is that true? Even if I clean it?

I’ve heard two-three weeks is best to avoid infections (though I’m not sure which ones)

I'd leave it in there if its clean. I've found that rabbits will naturally leave the nest at a certain age. Whenever they stop sleeping in the nest box at night (can range from 20 days to 30 usually) I take the box out. I do clean it at 10-12 days when their eyes open, when I flip the box onto its side

I do the same as @SableSteel. Whenever they stop using it, I pull it out (usually around 3 weeks old... 2 weeks is too early in my opinion, but it also depends on the weather). If you leave it in too long, they will start using it as a litter box potty corner. Also, it's important to clean it (completely empty and remake it on day 9-10) right before their eyes open to prevent nest box eye!
