I personally don't candle turkey eggs until day 25 when I am moving them to lockdown. I have found it very common for the first couple of eggs laid to be infertile no matter how much breeding has occurred. I do mark my eggs with a pencil (others use a black marker) with the date gathered and a code for the hen that laid the egg if known. I store mine through the 14th day before adding to the incubator.
Alright, thank you both.
