Ok I'm new to the incubator thing. Mine is coming soon. So I have googled how to tell bout the egg and the answer is candling the egg. I get that when its like 7 days fertile. But what do I look for when I take them fresh layed in my coop. Will I see a dark spot straight away or do I need to wait a bit longer to see. I'm excited and can't wait to start but don't want to put eggs in if there not fertile. Will they be ok out the fridge for a few days until I see a dark bit in them or do I just put them in my incubator any way and check them after a few days then if not fertile dispose of them.
