Generally speaking, an infertile yolk will be a brighter yellow than a fertile yolk. The albumen of infertile eggs is thicker than the albumen of fertile eggs. An infertile yolk is held in the center of the egg while a fertile yolk will sink near the point end.
Kuning telur yang bersenyawa(fertile) adalah lebih pekat kuningnya dari yang tidak bersenyawa(infertile).
Putih telor yang bersenyawa adalah lebih cair dari yang tidak bersenyawa
Kuning telor yang bersenyawa akan jatuh kebawah ,manakala kuning telor yang tidak bersenyawa akan berada di tengah-tengah telor.
The hatching process requires great exertion by the chick. The chick progresses through periods of activity followed by lengthy periods of rest. The entire hatching process requires 10 hours to 20 hours. Do not be concerned about the time a specific chick requires to hatch unless the process exceeds 20 hours.
Once chicks successfully leave the shell they should remain in the incubator until their feathers are dry. Ventilation should be increased. When more than 90 percent of the chicks are dry they should be removed from the hatcher. Excessive time in the incubator can dehydrate chicks. Remove chicks to a warm brooder and provide them with water and feed.
Eggs that remain unhatched for 1 day beyond the predicted incubation period should be discarded. Attempts to help a chick free itself from the shell often are unsuccessful. Chicks too weak to hatch themselves usually do not live. If they live, they usually will not thrive. Dispose of weak or deformed chicks humanely. These chicks should never be used for breeding purposes because these traits could be transmitted genetically to their young.
