When examining the lung fields of a normal CXR, the outline (silhouette) of the heart borders; the ascending and descending aorta; the aortic knuckle and the hemidiaphragms should be clearly visible. 1  All of these silhouettes, or structures, are in contact with a specific portion of the lung.
Perhaps the most important parameter is temperature â chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal) and 50 to 65 percent relative humidity (60 percent is often considered the ideal).uring the final three days of incubation, the eggs should ideally be located in a slightly cooler (98.5 degrees) and more humid (65 percent relative humidity or greater) environment to facilitate successful hatching.
What temperature do you need to incubate chicken eggs?   101.5 in a still air incubator 99.5 in a forced air incubator Also important For the first 18 days the humidity should be 50%-60%ish and the eggs should be turned â¦ an odd number of times, at least three.For the last three days the humidity should be about 65%-70%, and the eggs should not be turned.Josie.If you have a thermometer-about 100 degrees F is good.) Roll the eggs each day using m â¦ oist fingers (this provides the small amount of humidity required.) Chicken Eggs take approximately 21 days to hatch.
