You can candle an egg around 7 to 10 days into incubation to check for fertility. At this stage, a developing embryo may be visible as a dark area, along with blood vessels branching out. Candling too early may not provide clear results, as the embryo is still very small and may not be easily seen.

How can you tell if the eggs are fertile?

Do you have a Rooster living with Hens? If so, chances are, yes, the eggs will be fertile. If the hen is brooding, meaning she is sitting on top of the egg to keep it warm, then it's probably fertile, if not, then it's not fertile. In any case should you have a rooster and a hen together, and the hen lays an egg, and it doesn't brood, then you should keep the egg warm. I think to check just hold the egg up to a light lol.


How do you know a lizard egg is fertile?

You can "candle" them. Hold the egg in front of a light bulb and look for the yolk. It will be in one end or the other. If that's all you see, it is not fertile. If there is more dark area in the egg than just the end, it probably is fertile. It takes a while for the chick to develop, so let them sit for a while before you do this.

When do you candle a fertilized chicken egg?

You can candle a fertilized chicken egg anytime. There is very little to see for the first few days but after about day 5 you will see changes. It is best not to keep the egg out of the incubator for more than a few minutes and certainly no more than 20 minutes as they are susceptible to temperature changes and will not develop well if you let it cool.

Can you tell if an egg has a chick inside by weight?

After around 7-10 into the incubation period, (research this to check), it is possible to do something called candling. Candling is where you shine a light into the egg and look at the embryo forming. If there is nothing and the egg is clear, then the egg is infertile. If there is an opaque object in the egg, this is an embryo. Be careful though, because if you candle early in the incubation period you might be unable to see the embryo yet and mistake it for an infertile egg! When you choose a candling torch, make sure it's not one that releases a lot of heat because this could damage the chick. Good Luck!
