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.
6. Record the day and how many eggs you've incubated on a calendar. You should be able to estimate your hatch date based on average incubation times for the bird species you want to hatch. For example, chicken eggs typically take 21 days to hatch, whereas many duck varieties and peafowl may take 28 days.alibrate the incubator's temperature. You must calibrate the incubator to ensure the temperate is correct and stable at least 24 hours prior to incubating any eggs. 1  Make sure to adjust the incubator's thermometer so that it will measure the temperature around where the center of an egg will reach in the incubator.
