Wow! they are so hard to see into. Today is day 18 for 31 eggs I found in a nest. Candled them all and still just can't really tell if anything is there! I think I found 8 for sure. I marked the ones I think I see something in, and put them all back in the 'bator. Chicken eggs are so much easier! Does anyone know if there is a thread with guinea egg candling photos? Seems at day 18 I should see a little more than just a blob. Thanks!
