TX6 or TX7 -- Which One is Best for You?
Most of the TX7 models are used by specialized breeders for their Macaws, Cockatoos, Eclectus, etc., while the TX6 is primarily used in the schools for their spring science programs to hatch chicken, duck, quail or even goose eggs. The Classroom Incubation Kit includes the TX-6, along with all a variety of necessary accessories that make for a successful hatch.
What are the Similarities Between the TX-6 and TX-7?
Both units provide provide fan-forced air flow for even heat distribution around the eggs and can accept the optional automatic turner. Both have a set of thermometers and also enable hatching a variety of eggs that can be incubated and hatched. Each unit includes one turning ring of your choice.
What are the Differences Between the TX-6 and TX-7?
The two major differences between the TX-6 and TX-7 are found in the temperature control module and the thermometers that read temperature and humidity. The thermostat of the TX7 model utilizes a "Ten Turn" Potentiometer, whereas the TX6 model has a "Single Turn Pot." This means that the temperature on TX7 you can be fine-tune more easily and accurately for your specific requirements than on the TX-6. This is especially useful at hatching time when the temperature is usually lowered.
The thermometers on the TX7 are a higher grade Mercury thermometer than the small red "Spirit" alcohol thermometers used in the TX6. Since most TX6's are used in schools, these are supplied as they are easier for children to read and understand.
What is a Wet-Bulb Reading?
Since moisture is required for incubating and hatching eggs, the water bottle is used to let water pool in the base of the incubator. One of the thermometers should have a cotton wick on it that goes down into the water, making it a "wet bulb" thermometer. Humidity is the amount of water in the incubator that has evaporated in the air of the unit. The wet bulb humidity reading on the thermometer is not the same as Relative Humidity (RH) in percentages. Rather, it is the temperature of the water in the base of the unit. When used in conjunction with the incubator temperature, you can find the RH by use of the chart in the Hatching Manual which can be ordered separately. The Hatching Manual supplied with each incubator includes a more thorough explanation.
What Temperatures are Required
For most fowl, the incubating temperature should be 99.5° to 100° F. The wet bulb temperature should be 84° to 86° F. The combination of these two readings is equivalent to approximately 51% to 56% Relative Humidity. Different types of eggs require different settings for temp. and humidity. The thermostat is adjustable and will be able to achieve a wide range of temperatures.
Is Any Assemly Required?
Typically, Lyon Technologies incubators are pre-assembled to a certain point of completion. Since full assembly would add to the cost since it would require a much larger box and more shipping damage would likely occur, some simple assembly is required when you receive the unit. Instructions with diagrams are provided with the TX Incubators to make final assembly easy.
How Often Should Eggs be Turned?
Chicken or other fowl should be turned a minimum of 5 to 7 times a day. Using an automatic turner is recommended if you are away from the incubator for long periods of time.
The standard AT1 turner which is included with the TX-7 Automatic is best for serious breeders as this unit will turn the eggs once every hour,taking only 30 seconds or so to complete the turn. This simulates the way the hens turn their eggs. The AT3 turner which comes with the TX-6 Automatic turns the eggs continuously, but extremely slowly. It is effective for basic eggs such as chicken eggs for school projects, but exotic birds breaders will get better results with the automatic turner of the TX-7.
Why Should Eggs be Turned?
Turning eggs keeps the embryo from settling towards the bottom of the egg and sticking to the shell. If the embryo were to stick to the shell only the part of the embryo touching the shell would get sufficient oxygen, leaving the rest of the developing embryo deficient in oxygen. Turning the egg allows the absorbed oxygen to be spread uniformly within the egg. Mother hens instinctively know to get off the nest to turn the eggs at intervals.
