A low-iodine diet will improve the. reliability of the test results. If you eat too much iodine before the test, the results might be. wrong (false negative). On this diet you can eat no more than 50 mcg iodine per day. We encourage you to. calculate and plan your diets carefully to achieve this goal. The following are some ideas for. doing this, followed by sample diets on the reverse side.
Turn the eggs to a new position once daily until placing in the incubator. Hatchability holds well up to seven days, but declines rapidly after that. Try not to store eggs more than 7 days before incubating. A 14 day storage reduces hatch to near 50% and after 3 weeks of storage, hatchability drops to almost zero.Plan ahead and have a regular hatching schedule to avoid storage problems and reduced hatch percentages.early all fertilized chicken eggs will hatch after 21 days of good conditions - 99.5F Â°(37.5 Â°C) Eggs must be turned regularly (usually three to eight times each week) duri â¦ ng the first part of the incubation.
You may be able to see the chick moving about inside of the egg as it grows larger. You should candle all of the eggs on day 5 and again on day 10 of incubation, to see if the eggs have developed further or if any embryos have died within the egg. If the eggs are still viable on day 10, you should see darkness (the chick) covering most of the inside of the egg. Infertile egg Fertile egg Fertile egg. Infertile or clear eggs will appear empty except for a yellow yolk and the air pocket.
