For logistic reasons it is sometimes necessary to move the eggs during the incubation process to another location. This can be for instance needed when either setters or hatchers in a hatchery are under construction or have limited capacity, and machines at another location need to be used for the last part of the incubation process. Also for hatching on the farm it is necessary to transport incubated eggs.
Incubated eggs can be moved during the incubation process with a number of precautions.
- Eggs can be taken out of the machine and be transported at any moment during the incubation process between 12 and 18 days.
- The time out of the machine can be up to 48 hours.
- Keep the eggs on the setter trays during the transport and place the trays in either farm trolleys or keep them on the setter trolleys.
- Do not transfer them to hatcher baskets before transportation as in the hatcher baskets they tend to break more due to the movement of the truck.
- DO NOT take them out of the trays and put them into boxes as they will get overheated.
- DO NOT cover the trolleys with plastic or whatever as they will get overheated, the eggs need to be able to lose their heat.
- Put the temperature of the truck on approximately 23-25 oC.
- Transport at incubation temperature is in principle possible but is not advisable as the eggs can easily get overheated due to the differences in air flow in the truck.
- After arrival at the hatchery put the eggs back into the setter and follow the normal procedure, or transfer them to hatcher baskets and put them into the hatchers if they are already at 18 days
- Do not transfer the eggs before 13 days as at 12 days it is still beneficial to turn the eggs. After 12-13 days there is no problem to stop the turning so transfer to hatcher baskets can be done.
- After transport the eggs are cold (if transported at 25oC), so candling with a so-called “heart beat machine” will not work as the heart beat (heat) will not be detectable. Candling with light is possible
- Due to the transport the hatching moment will be delayed (if transported at 25oC). Add roughly 2/3 of the time of transport to the hatching time. So if the eggs are transported for 12 hours, add 8 hours to the normal hatching time.
- The hatchability of those transported eggs will be normal, and often the chick quality tends to be better as some of the overheating that often occurs in normal incubation processes will be compensated by the transportation at lower temperatures.
