i had hen go broody so i thought i would see if she would hatch a few eggs. i do not have a roo. so i had to find fertile eggs. i finally found some, but 3 were the fridge and was fresh from the coop. will the fridge hatch? they are 1 to 4 days old. also i marked them with a permenant marker so the kids or wife would not collect them. will marker hurt the eggs? thank you.
