Here's some pics of the first clutch I've ever had to care for. There's 26 total split 13 in each container. So is that too many are they too close together? Do the eggs look fertile? They feel nice and firm and are nice and oval but I don't know. How soon can I candle them to see if they are viable? Thanks for any help.
