Eggs must be turned at least 3 to 5 times per day and up to 12 to 24 times per day. There is no conclusive evidence of the best position or turning times for ratite eggs. We have used poultry information here and modified it to provide a starting point for these species. Three to 5 days before eggs are expected to hatch, transfer them to a separate incubator used only for hatching. Do not turn the eggs after transfer.
Most growers weigh eggs weekly to monitor water loss.
If the eggs are not losing the proper amount of moisture, you may need to change the relative humidity. Many producers maintain several incubators at different humidity levels and move eggs as needed. Others cover parts of the shell with tape or fingernail polish to reduce water loss, or sand away part of the shell to increase water loss. These practices are easy with a few eggs, but become impractical when more eggs are produced. Their effectiveness is unproven.
