You may get lots of different advise.we kind find our own style after a bit.I want to joinI have some eggs due around the 10th. We set 24 barnyard mix eggs and 11 store bought fertile brown eggs. One of those I culled because it was leaking. I quickly held a light over them all last night and saw lots of veining! It looked like some blood rings, too. Tonight is day 7 so I will candle "for real". At that point should I cull the blood rings and clears?![]()
I do not candle until day 11.....for me, 7 is a little early for throw aways..........
and I do not dump anything but clears.usually on day 18 unless it smells.
I've had to many weird things happen.
I do lock down until day25.One time was slow dumping the eggs that did not hatch
and when I went to throw them in the garbage,,,(day 27) there was a chick staring at me...........

Named her # 27......
I have had a rotton eggs only one time............. good Luck to you....................
