Wide mediastinum is caused by aortic rupture or mediastinal hematoma, but poor radiographic technique can lead to a mistaken diagnosis. The plain chest film and the aortogram are essential for the proper diagnosis of widened mediastinum in trauma.
1 Temperature: Chicken eggs should be incubated at a temperature between 99 and 102 degrees Fahrenheit (99.5 is often considered to be ideal). 2  Avoid temperatures outside the 97â103 Â°F (36â39 Â°C). 3  range. 4  If the temperature remains beyond either extreme for several days, hatchability may be severely reduced.
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.
