It will then be necessary to retire that rooster should you wish to continue raising chicks. A quick and easy way to check the ability of your rooster to continually fertilize his hens is through candling.
This method has been practiced for many years through the use of specialized lights sold at farm and garden stores held up to the egg. The goal is to locate the embryo to confirm a life is growing inside. In some cases, instead of being able to the see the actual embryo, the egg will instead appear opaque, which is another sign of a successful mating.
As you candle eggs over the course of a few days, it will be possible to observe a growing embryo and shrinking air sack, although soonest visible are blood vessels.
If the egg is not fertilized, the yolk will appear to float free and have a more uniform coloration. An alternative to candling involves actually cracking the egg open to check for fertilization, which is counter-productive if you wish for those eggs to hatch. As you crack the egg, take care not to bust the yolk as this will make it difficult to see the telltale signs of fertilization. Pour the shell contents into a bowl or pan of contrasting color and look for a white spot.
The practical implications of this book were first impressed upon me by two unlikely suspects: my Black Copper Marans BCM rooster, Max and my 4 year old daughter. Max came to me from Louden Farms in Ohio as a fertilized egg early last July. I quickly became fond of this awkward singleton, but before long, it became apparent that he was a rooster, and I could not keep roosters. I knew he would have to go, but I could not resist the temptation to keep him long enough to breed him to my Marans hens.
Having Marans hens that were laying consistently dark, chocolate eggs that would make the Easter Bunny envious, I was anxious for Max to mature in order to breed. I had no idea how I would keep him without alienating my neighbors, but I had to try, at least for a little while. When Max began mating with the ladies in October, I regularly checked the BCM eggs for fertility and by mid-November, it was game time.
In early February, an elaborate plan evolved to return Max to his homeland, Louden Farms, some miles away from us. It involved two days, three states, three cars and a limousine. Saddened at the thought of parting with my beautiful flock-master, I began sharing photos of Max and his impending trip with my Facebook fans, which prompted questions about when my chocolate egg well might run dry. If the hen laid an egg shortly before, the mating will likely fertilize her next egg.
To look for the bullseye, crack an egg open into a dish. You will be able to see a small white disc called the blastodisc. If this is fertilized, it will have a cohesive, circular shape with concentric circles.
This gives it the distinctive bullseye appearance. Fertilized chicken eggs have to be kept at precise humidity and temperature levels for a chick to develop. Some people believe fertilized chicken eggs will taste differently and be more nutritious than unfertilized ones. There has actually been researched conducted in order to scientifically refute this idea.
According to scientific study, fertilized chicken eggs will taste the same and have the same nutritional value as unfertilized eggs. Some believe that eggs with a point will produce male chicks while rounder eggs will produce female chicks. There is no scientific evidence to support this. All fertilized chicken eggs have about a 50 — 50 chance either way! Similarly, the color of an egg is determined by the breed of the chicken that laid it.
Research shows that there is little difference between eggs of varying colors besides the genetics that went into their making. Another commonly held belief is that the incubator temperature can influence the gender of fertilized chicken eggs. Conversely, setting the incubator temperature half a degree lower should result in more female chicks. While this seems like random speculation, it might actually be true.
Some research shows that variations in incubator temperature may in fact influence the gender of developing embryos. Cracking open an egg can occasionally reveal a spot of blood in the yolk. Some people believe this only happens in fertilized chicken eggs. Instead, it can occur when a blood vessel pops while the egg is developing inside the mother. A burst blood vessel can be the result of genetic factors or vitamin A deficiency. It can also be a random event.
Fertilized chicken eggs can be surprisingly fascinating. Some information about them is fairly common and obvious, but they can also surprise you! This wait time allows for all eggs hatch at approximately the same time. They tend to just continually accumluate eggs as they sit which is really annoying.

It is possible to buy fertilized eggs 3. Not all roosters are fertile 6. It can take a while after mating for hens to become fertile 7.
Hens can stay fertile for a while after mating 8. Eggs are surprisingly hot 9. Hens might be able to tell which eggs are healthy Eggs contain everything for chick development Candling can help you see if an egg is fertilized You can also tell if an egg is fertile by looking for the bullseye You should never buy shipped hatching eggs Fertilized and unfertilized eggs taste the same
