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.
1 Humidity The best humidity level at which to store eggs is between 75 to 85% RH to avoid significant drying out of the egg before incubation. 2  Time in Storage It is generally considered that eggs should not be kept for more than 7 days prior to incubation.3  Beyond this time chances of hatchability decrease considerably. Collection of Eggs Generally the best time to collect eggs is before 9am, and to check again at lunchtime. 2  Eggs left in the nest for much longer than 24 hours tend to be poor hatchers. 3  Egg Shape, Shell Texture and Quality Some naturally misshaped eggs have lower than expected hatch rates.
