Janoel12 incubator

The Janoel12 (or JN12) incubator is manufactured by Yueqing Janoel Electrical Co., Ltd, also known as “Chonka” or “Guangzhou Kawa Electronic Technology Co., Ltd.”.

For automatic turning, it rolls the eggs continuously right and left across the incubator. The instructions imply that it takes 9 eggs, but if the eggs touch sides at any point, they can become stuck and stop turning so it is important to ensure that they do not touch the sides of the turning frame.

For manual turning, I sit the eggs fat end up in egg boxes, put a rubber band around the incubator (so that the lid is firmly attached to the bottom) and turn the whole incubator, popping the front or back up on a wooden baton. For manual turning, I also remove the turning rod because there is a chance of it damaging the eggs (this has happened twice to me).

Here is how many eggs I found it can take using both methods:

Poultry Automatic turning Manual turning
Chickens (medium eggs) 6 15
Chickens (small eggs) 9 15
Ducks 6 12-15
Quail 20 48

The instructions are a bit funky, so here is my interpretation of them:

Incubator operating instruction

  1. Before you start

    Unpack the box and check the incubator. Check whether all of the parts are present.

    When ambient temperature is lower than 20°C, you should take measures to keep the temperature more stable. Wrap the bottom half of the incubator in cloth (towel or a sheet). Make sure that the air hole on the top is not covered!

    Use a thermometer to calibrate the temperature display before use. You can adjust the CA setting to correct it.

    The incubator can be used after a 24 hour trial run during which you should aim to finish calibrating the incubator.

  2. Operating instructions

    1. Place the bigger plastic mesh into the incubator, railes facing up (fig.1).
    2. Put the movable egg tray (fig.2) onto the mesh, between the rails, with the loop facing upwards.
    3. Insert the egg tray dividers (fig.3) into the movable egg tray as needed. Once the eggs and the dividers are inserted, the eggs should all line up end to end with 2mm of space to the side between the egg and the next rail. You may end up with a spare space on the end which is unused.
    4. When closing the cover (fig.7), the automatic turner rod must be inserted into the loop slot of the moveable egg tray, so that the egg tray can move to turn the eggs.
    5. Switch on the power supply after closing the cover, and set the temperature according to display instructions and Incubator technology.
    6. 3 days before the eggs are due to hatch, remove the eggs, the tray and the large mesh. Replace the large mesh with the small mesh that has feet, placing it feed down into the incubator. Replace the eggs into the incubator and add a small amount of water to the base to increase the humidity for hatching.
  3. Safety information

    1. Only the power supply marked on the incubator can be used, which is 220-240v
    2. Do not put anything on the power cable. Place the power cable where it will not be stepped on.
    3. Make sure that the socket and any extension leads that are used are not overloaded.
    4. If the incubator is smoking, or produces an abnormal smell or unusual noise, switch off the power supply and unplug the incubator. Contact the seller or a maintenance centre to enquire about repair.
    5. Do not touch the power line with wet hands.
    6. Do not expose the incubator to rain or sunshine.
    7. Make sure that the power supply is switched off before cleaning the incubator.
    8. The incubator can be used only in a well ventilated room.
    9. Do not block the air hole when the incubator is switched on.

  1. I have set the temperature and it stays at temp but not seen eggs turn. Does the machine turn on its own or do I have to do something to make it move ?

    • Hi Dawn! If you have set up the machine according to the instructions, it will move the black cradle left and right very slowly, but constantly. The turner rod needs to fit in through the loop on the side of the cradle for it to work properly.

      You also need to make sure that the eggs have 1-2 mm between them and the divider so that they can roll. Before starting incubation, I check that they are able to turn by moving the cradle by hand, left and right, a few times. If any of the eggs become stuck, then the eggs or dividers need to be re-arranged in some way.

  2. I have recently purchased one of these. I’m wondering how the automatic turner rod works as it doesnt seem to be moving?
    Thank you.

    • The automatic turning rod moves very slowly! To test it, turn the temperature right now, leave the lid upside down, note the position of the turner rod, switch the incubator on and check on it ever 5 minutes for half an hour or so. After half an hour, you should have seen some progress: the wheel should have moved so that the rod by 180°.

      If the rod position does not change when the incubator is running, then there is something wrong with the rotator mechanism.

  3. Hello, Could you please confirm the correct temperature the incubator should be set for hatching eggs? Also where do you add the water and how do you check the humidity?

    Thank you

    • The temperature that you need to use depends on the species of the egg and your incubator. For example, I chose to use 37.6°C for chicken eggs. You should research what temperature you should use based on what other people use and make your own decision from that.

      When I used this incubator, I used a digital hydrometer to check the humidity and a large bottle cap for the water. The instructions for the incubator say to put the water into the bottom, but I found that that gave me a humidity which was too high.

  4. How do you set the humidity as there is a HU sign and at what temp should I have it on. It’s day 1 and I have added 100ml of water like it said,and my temp is 38.2

  5. Hello, the temperature that I should put on hen on day one is 38? Or 37,5 and you have to adjust some parameter as ca ls or everything comes from factory

  6. Hello I’m having issues with the incubator, I have ducks and chickens I followed all instructions and have well knowledge of the incubator. Everyday I check to make sure there is water in the incbator to make sure humidity is there for thbut eggs to hatch easily. But recently I have noticed duck eggs are harder and even with water in the bator the ducks can’t hatch out of the eggs and die, out of 9duck eggs i have tested each born on different days as eggs were out in the bator on different days, so far only 3 have successfully hatched but with one with a crooked leg from being in the egg. Th other 6 were ready to hatch but when I check on them th next day when they should have been out of the egg is dried up and the ducks are dead because they can’t break out. Very disappointed to see this happen to my ducks I love raising, is there anything I can do to stop them from dying?

    • Did you resolve this? Very excited as our baby ducks are peeping in shell and it’s jumping a bit. Wanting to be sure I do everything right so as to not lose them. This is our first time using an incubator and hatching eggs.

  7. 3 thermometers inside. None of them are over 93 F. I did adjustments, set to 40. No change in 48 hrs. Omg!

  8. Hi I’m looking for a part to go with my incubator it’s the bit that moves the tray backwards and forwards. It’s made of plastic and the plastic bit has cracked. Can’t you help or tell me where I can get one from thanks
