How do you know if your iguanas eggs are fertile?
Some women say they knew right away, but there is no scientific way of knowing; other than a blood our urine test. ANSWER Actually, there is no scientific way of knowi…ng if an egg is fertilized. Obviously, if you become pregnant then an egg did get fertilized but pregnancy does not always occur. I have read that anywhere from 40-80% of fertilized eggs not not actually implant and are just passed in the woman's period. In this case your egg could have been fertilized and you would never know it.
One view: She will set on them all at first, but if she doesn't feel heat coming from the egg which the growing embryo gives off, she will either throw it out of the nest or …eat it. If you keep disturbing her to check, you will run the risk of upsetting her and she will leave the whole nest. Another view: She doesn't know. She will sit on infertile eggs as readily as on fertile ones. In fact, if she is in the mood, she'll sit on golf balls. Let her set on them for a week and then use a light to check to see if any thing is there.
you know if the egg is fertilized if you missed your period.
yes it can
Symptoms of pregnancy will vary. Many early signs mimicpremenstrual symptoms. The best way to tell if you are pregnant isto take a pregnancy test once your period is late.
You can candle eggs in order to determine if they are fertile or not as long as the eggs are at least 7 days old. Candling process can be found on the web.
Answer . \nThis is hard to answer, are you meaning how do you know you are pregnant, or how do you know it is the perfect time of the month? When you look at a calander a…nd keep track of your period, you will have an answer as to when it is perfect time for your egg to get fertalized. \nhttp://www.drmirkin.com/women/8786.html\nThis web site will explain the timing of your egg.\nIf you're asking about if you are pregnant or not, best to wait at least a month if not more before taking a test. However, some believe you can find out within 48 hours after sex.
If after 24 hrs the egg is not a white/opaque it probably is fertile.
As a consumer you may think that it is difficult for you to know ifthe eggs you buy are fertilized. There are no exterior or outwardsigns on the egg, and finding the germinal …disc (also referred toas the "bullseye") on the egg yolk is not something many people cando, as it is so small. However, nearly all eggs sold in grocerystores are infertile, because the hens that lay those eggsgenerally live their entire lives in small enclosures on factoryfarms and never see a rooster. Free-range eggs, those from hens notkept in such enclosures, will be labeled, and most farms thatproduce free-range eggs still restrict hens from being nearroosters, but some will label their eggs as being produced withroosters in the flock. Only those eggs produced with roosters inthe flocks can possibly be fertilized. If you buy eggs from a local farm, and they have a rooster amongthe flock, you can be pretty sure the eggs you get are fertile.Fertilized eggs are really no different nutritionally, than thenon-fertile eggs purchased at a supermarket. The only differencesin taste or nutrition between supermarket eggs and farm eggs aredue to the wider variety in the hens' available diets on farms,which allow them to produce richer-tasting, more nutritional eggs.
all you have to do is hold the egg up to the sun or get a LED light and shine the light through and if it has red in it, it means its fertalised. you can also see a shadow in …the egg
There is no way to look at the outside of an egg and tell if it is fertilized. If the egg has been under the hen for several days then you can candle it (shine a strong ligh…t into it) and look for embryo development.
After day 5 of incubation you can candle the egg to see shadowy changes within the egg. There are no outward indicators of fertility with chicken eggs. Candling eggs means t…o shine a bright light into the end of the egg and observe the development of the embryo within. A non fertile egg will show no shadows within the shell.
Either by getting pregnant or by a doctor retrieving the eggs and observing them under a microscope, when sperm is added to the petri dish or by doing specific testing.
After the eggs have been sitting for awhile, use a flashlight and put it on the side of the egg which is not facing you and shine the light through the egg. If you do not see …a dark, small object inside the egg then the egg is not fertilized.
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 m…ore 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.
Not immediately. Once the embryo develops to such a size that movement can be felt then the Goose knows, however she may continue to sit for a few extra days, depending upon t…he number of eggs in the batch. Have you observed a goose discarding what seems like a healthy egg from a clutch ?
Week # . Typical changes/signs . 1-4. Appetite remains pretty steady. Increased restlessness starts, or continues if started before egg development.. 4-5. Appetite starts… to falter as eggs begin to compress intestines and other organs. May eat only small amounts every couple of days or less. Water intake increases. Feces become very small and appear only the day or two after the last food intake. Urates may become thicker, yellowier. May become quieter during this period, basking more. Previously stand-offish females may be more receptive to petting/attention, while tame females may become more prickly about physical contact.. 5-6. Eating intermittently, only small amounts. Drinking deeply daily or every other day. Urates and feces affected accordingly. Despite reduced food intake, there is no apparent loss of weight (the eggs are taking up some of the space formerly filled by the well-stocked, but now depleting, fat pads).. ~6.5-7. When stroking the iguana along the sides of her abdomen, you may begin to feel two soft swellings, one in front of the other (as you stroke from ribs towards the front of where the hind legs join the body). These are eggs.. 7.5-8+. Tail may be getting thinner (in the hip area and down the tail). Body still broad across the abdominal area from the developing eggs. The bulges previously felt when stroking the sides may now usually be seen to cause small outward bulges along the sides. It is usually 5-7 days after you can see the eggs bulging from the sides that they are ready to lay....
