INCUBATION 101 🐣
Before ordering fertile eggs, make sure you understand your incubator and have everything required for both incubation and hatch day.
🌡️ Don’t rely solely on the incubator display
Purchase an independent thermometer and hygrometer before buying your eggs. Incubator displays can be inaccurate, and even a small difference in temperature can affect development.
Place your independent instruments at egg height, run the incubator empty before setting eggs and allow enough time to check that the readings remain stable.
📖 Follow the instructions for your specific incubator
There is no single setting that suits every machine. Some manufacturers recommend approximately 37.5–37.7°C, while some incubator designs specify temperatures closer to 38°C.
Always begin with the instructions supplied for your exact make and model, then compare the machine’s readings with your independent thermometer and hygrometer. Don’t automatically use settings copied from someone with a completely different incubator.
🔄 Remove the egg turner at lockdown
Chicken eggs should stop turning at approximately day 18 so the chicks can position themselves for hatch.
Remove the automatic turner and transfer the eggs to the proper hatching tray or floor supplied for your incubator. Leaving turning equipment inside can create trapping and injury risks for newly hatched chicks.
The eggs and chicks must sit on a clean, dry, stable hatching surface above the water reservoirs—not on matting placed directly in water. Chicks can become wet, chilled or trapped, and open water creates a drowning risk.
🔦 Candle throughout incubation
We recommend candling chicken eggs at approximately:
• Day 7 — check for early development
• Day 14 — monitor continued development and identify possible quitters
• Day 18 — final check before lockdown
Without checking at different stages, it can be difficult to distinguish an infertile egg from one that began developing and stopped early.
Dark Marans eggs and heavily pigmented shells can be difficult to see through. If you’re uncertain, do not discard the egg based on guesswork—mark it, monitor it and compare again at the next candling.
🐥 Prepare for hatch day before hatch day
Before lockdown, make sure you have:
• the correct hatching tray or floor
• a clean, non-slip surface where required
• water safely contained in the designated reservoirs
• accurate temperature and humidity readings
• ventilation set according to the manufacturer’s instructions
• the turner completely removed or disabled
Fertile eggs can only provide the potential for a chick. Incubator accuracy, temperature, humidity, turning, ventilation and hatch setup all play an important part in what happens next.
Read your manual, prepare your equipment before ordering and never be afraid to ask questions before setting your eggs. A little preparation can prevent an awful lot of heartbreak. 🤎
