This ensures even temperature exposure, addressing potential hot or cold spots within the incubator. Consistent turning is crucial for preventing embryos from sticking to the shell membrane.
Automatic Egg Turner Operation
The Little Giant’s automatic turner effortlessly rotates eggs, eliminating manual handling. Confirm the motor functions correctly, initiating movement as expected. Observe a full rotation cycle to ensure all eggs are adequately turned.
While convenient, don’t solely rely on automation; supplemental manual rotation is recommended for improved results. This addresses potential uneven turning and ensures consistent embryo development.
Manual Egg Turning (If Applicable) & Daily Rotation
For models without automatic turning, or as a supplement to the automatic system, manual rotation is vital. Gently turn each egg 180 degrees, marking one side with an ‘X’ to track completion.
Perform this rotation at least three times daily, ensuring even exposure to warmth. Consistent daily rotation, even with an automatic turner, improves hatch rates by preventing sticking and promoting development.
Egg Candling and Observation
Candling allows you to monitor egg development without opening the incubator. Use a bright flashlight in a darkened room, shining through the eggshell.
Look for visible veins indicating fertility, typically appearing around day 7. Infertile eggs will appear clear. Continue candling periodically to remove any eggs that have stopped developing, maintaining incubator hygiene.
Candling Techniques
Effective candling requires a dark environment and a focused light source. A bright LED flashlight works well. Gently roll the egg across the candling surface, observing for vascular development.
Hold the light firmly against the shell, avoiding excessive pressure. Candling is best performed after day 7 of incubation. Consistent candling helps identify and remove infertile eggs promptly.
Identifying Fertile Eggs
Fertile eggs exhibit visible vascular development – a network of red veins radiating from the yolk. This becomes apparent around day 7-10 of incubation. A clear egg, or one with a simple ring, is likely infertile and should be removed.
Observe for consistent growth of the vascular pattern. Darkening or lack of development indicates a non-viable embryo. Careful observation maximizes hatch success.
Hatching Process

Around day 18, initiate “lockdown” – cease egg turning. Maintain consistent temperature and slightly increase humidity to aid pipping and hatching. Resist opening the incubator during this critical phase.
Allow chicks to hatch undisturbed. The crowded hatch area of some models requires patience. Once dry and fluffy, chicks can be removed. Proper lockdown ensures optimal hatching conditions.
Lockdown Procedure
Three days before the expected hatch date, begin lockdown. Stop the automatic egg turner and remove the quail rails. Increase humidity by adding water to the trays, but avoid wetting the eggs directly.
Crucially, do not open the incubator unless absolutely necessary, as this disrupts the humidity and temperature. Maintaining stable conditions is paramount for successful pipping and hatching.
