Hi everyone.We are new here and am happy to have found you.We are trying to hatch eggs of various ages and candle our eggs alot.We have one egg that is due to hatch Sun/Mon that has really been a good experience watching.We have recently added a few new eggs and upon candling cannot find an air sac in some of the eggs.Any ideas on why we can see the air sac in all the other eggs but not a few?Some of the eggs in the same time frame have a sac.The eggs are from our own chickens which just started laying recently.Thank you for the advice.
Are they really fresh eggs? If yes, you cannot see the air sac in fresh eggs. It has not had time to develop.
The eggs are put into the incubator within hours of being laid.I was worried because we get three eggs sometimes and you can see the air sac in two sometimes but not the third.
Not really sure then. You could wait it out and see if some of the liquid inside the egg evaporates off of it during incubation. I would do a dry hatch to ensure that the liquid evaporates though.
We have also notice a tight blood ring in the middle of one of the eggs.Should we wait a little longer to see if this clears up or toss the egg?There is movement inside the egg and we can see other blood veins that look like the "spider veins".The egg is 2 weeks old.Could it possibly be because the egg got too hot?
If the chick is moving, it is not a blood ring. Blood rings are a sure sign the embryo is no longer growing (died) Maybe it's just some veins?
The blood ring is usually a sure tell way of determining a bad egg. It most likely has bacteria in it, and the chick wouldn't survive development with the presence of the bacterium.
We just candled the egg again and the ring is smaller and the embryo is still moving.Could it be because of laying on the egg carton and getting too hot?The thermometer in the bator is usually pretty steady but not long ago the temp really spiked(102) and after that is when we noticed the ring on the inside of the shell.The ring appears to be stuck to the egg.As long as the embryo is moving should we let it be and hope for the best or should we toss it?
