Attention

1. Ensure disconnecting power before opening the cover.

2. Hatching eggs must be fertilized eggs.

3. When finish hatching, the cover and bottom must be air-dried separately to prevent the electronic components from being damaged

by internal moisture of the machine for a long time.

Incubation Tips:

1. Please choose fresh fertilized eggs laying within 4-7 days generally. Keeping fertilized eggs at 10-

15℃ is recommended. Washing or putting it into fridge will damage the powdery substance

protection on cover ,Which is strictly prohibited.

2. Ensure fertilized eggs surface are clean without deformity, cracks or any spots.

3. Incorrect disinfection mode will reduce hatching rate. Please ensure eggs are clean and without

spots if without good disinfection condition.

4. Ensure eggs are pointy side down when hatching.

5. Please add water to the machine every 1~2 days (it depends on the environment humidity and

water content inside the machine).

6. Manually turn eggs twice per day gently and slowly (Keeping fertilized eggs pointed side down,

swing left and right side at 45°around 3-4 times).

7. Do not test eggs in first 4 days. Incorrect egg testing timing will lead to temperature decline,affect

eggs' early development.

a.Test eggs in 5th-6th days,check the fertilization of the eggs,take out unfertilized eggs, scattered

yellow eggs, dead eggs

b.Test eggs in 11th-12th days, check inner eggs development. Well-developed embryo is enlarged

with blood vessels inside, and the air chamber is large and sharply demarcated.

c.Test eggs in 16th-17th days, put pointy side of egg toward to light source.Well-developed

embryo is getting larger and filled up the eggs inside with dark area mostly. Dead egg is with

blurred blood vessels,yellow air chamber around, unclear boundary between egg inside and the

air chamber.
