 * Aim**: My aim is to make an incubator that will hatch fertile chicken eggs


 * Question**: Will the eggs hatch in the incubator with the light bulb?


 * Procedure**:
 * To see if the eggs will hatch?
 * Will the cold egg still hatch?

By the time you have got your eggs your incubator should have been running for at least 24 hours. A week is even better. This gives you time to learn whats going to happen in your incubator and allows you to make any necessary adjustments before setting your eggs. A common way to ruin hatching eggs is to put them in the incubator without having it properly adjusted. If the eggs reach a internal temperature of 105 .F. degrees the chickens will die. Remember it is the internal egg temperature not the internal incubator temperature. The temperature in the incubator changes constantly rising and lowering. the temperature inside the egg will be an average of this temperature swing in your incubator. When you are incubating eggs in January and February it will be very difficult to maintain a humidity that is as high as you like. Thats because the outside humidity is so low. When you are incubating in June and July the outside humidity is usually much greater and the humidity in your incubator will most likely get much higher than you would like. Hatching problems will change as the season progresses. If you are doing things the same way in july as you were in January, you have to expect different results. Your incubator humidity changes directly according to the outside humidity. If it is low outside it is low in the incubator, if it is high outside it is high in the incubator. To adjust these problems you need to change the surface area of water in your incubator.
 * Research**:
 * Method**:
 * 1) Get a cardboard box
 * 2) If you want you may spray paint it black
 * 3) Cut a square in the front of the box with the craft knife
 * 4) On the right side cut a small circle to houze the light bulb
 * 5) Stick the piece of glass on the cut out square
 * 6) Unscrew the bottom of the holder and put it through the hole
 * 7) Screw the other side of it on
 * 8) When you have screwed it on put the light bulb in the holder
 * 9) Connect the light bulb to the power cord
 * 10) Connect the temperature control unit so when the incubator gets up to 35.5 degrees C the light will cut off and when it gets to 34.5 degrees C it will turn back on again if you do not know how to do this get an adult that does do not move on until the light is working
 * 11) If the box flaps are touching the light there is a big chance that the flap will burn what you do is you put a bamboo twig or a skinny steel rod across the bulb then it will not burn
 * 12) Fill the incubator with saw dust
 * 13) Place the thermometer in the incubator
 * 14) Put a glass of water in the incubator for some humidity
 * 15) Weigh the eggs mark the eggs and record the temperature before putting it in
 * 16) Leave the incubator running for at least 24 hours before you put the eggs in
 * 17) After the 10th day make a cone out of card and put the torch on the bottom of it put the egg on top and see if you can see a little circle moving side to side if you can put it back in the incubator if you cant go out side, dig a hole and put the eggs in it but be careful not to crack it or it will not smell nice
 * 18) **Research**:

This is plain and simple, but it is the most important part about hatching. Still air incubator (no fan) should be 101.5 F degrees measured at the top of the eggs. Fan forced incubator: 99.5 F degrees measured anywhere in the incubator 18.Craft knife
 * Research:**
 * Humidity**: 60-65% for the first 18 days, 80-85% for the last 3 days. The combination of poor humidity and temperature will definitely cause problems at hatch time. if your temperature is not accurate you will definitely have problems at hatch time. The bigger the difference from the proper temperature, the bigger your problems will be.
 * Equipment/Apparatus**:
 * 1) Cardboard box
 * 2) 75w light bulb
 * 3) Power cord
 * 4) Temperature control unit (buy it from Jaycar)
 * 5) Saw dust
 * 6) 6 fertile chicken eggs
 * 7) Bamboo twig or steel rod
 * 8) Spray paint (optional)
 * 9) Masking tape
 * 10) Square piece of glass
 * 11) Silicon rubber
 * 12) Light bulb holder
 * 13) Thermometer
 * 14) Gram scale
 * 15) Small glass of water
 * 16) Bright LED torchX

The incubation period for chicken eggs is 21 days. You should turn your eggs at least twice a day for the first 18 days, and stop turning them after the 18th day. This allows the time to orient itself inside the egg before hatching. After day 18, **KEEP THE INCUBATOR CLOSED** except to add water. This will help bring the humidity up to help the chickens hatch. I know it is hard not to open the incubator when it is very close to hatch time, but it’s not good for the chickens. Humidity is checked by way of a hygrometer (wet bulb thermometer). A hygrometer is simply a thermometer with a piece of wick attached to the bulb. The wick hang in water to keep the bulb wet. When you read the temperature on the thermometer and hygrometer, you must then compare the readings to a chart to translate from wet-bulb/dry-bulb reading to percentage humidity. From the relative humidity table... 60% humidity read about 87 degrees F on a wet-bulb at 99.5. degrees. 60% humidity reads about 89 degrees F on a wet-bulb at 101.5. degrees. 80% humidity reads about 93 degrees F on a wet-bulb at 99.5. degrees. 80% humidity reads about 95 degrees F on a wet-bulb at 101.5.

====Please Note:  ==== ====This table is different from the one outlined in the above Science Fair booklet. There will be__**no extensions**__ given, Class time will be given for writing up aim, hypothesis, instructions, explanations, diagrams, tables etc and putting displays together. Parents please support your child with carrying out their experiments as this will be the main element of their homework during Science Fair. ====
