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.
For more info and tips on managing these see here. Before putting your eggs into an incubator, plug it in and make sure the temperature is steady. In a forced air incubator (with a fan) the temperature should be 99-99.5*F.In a still air incubator the temperature should be slightly higher, 101-102*F measured at the top of the eggs. I use a thermometer and a hygrometer (which measures humidity) in my incubator.or more info and tips on managing these see here.
