Kiki candles daily.How many days do you wait until you candle? I set 6 eggs jan 21 and none of them look viable no air sacks or nothing.
I usually just candle at day 7 to pull clears and prevent exploding eggs and day 14 at lockdown to check for late quitters. Lots of pictures on the net and this site to show you what to look for. I candled at day 3 cause I was curious this time.
At day 5 you should see red or hopefully blood vessels and a large blob. If the egg is clear and glowing yellow, it wasn't fertile.
Use your phone flashlight if you don't have a 500 lumen flashlight, but preferably higher power to see into dark shells. I got a 1000 lumen flashlight just cause I wanted to.
