When to toss?

[Teresaann24]

I am doing a test hatch for a great BYC member. I am on day 5 and out of 42 eggs 3 have nothing in them they look just like the day I put them in. Now 2 days ago on day 3 I candled and out of 42 I could only see growing in 35 of them which left 7 looking non growing Now today after candling out of those 7 I did not see anything 4 are growing and three still look the same as the day I put them in. When should I toss the three with no growth remember I am on day 5.

I don't toss anything until day 10 or so, just to be on the safer side of things. BUT I wouldn't candle every few days, over handling can kill embryos...
