Which of the following is not something that should be considered desirable when selecting a scale?

When selecting a scale for avian practice, several factors contribute to its effectiveness and usability. Portability is desirable because it allows the practitioner to easily move the scale between locations or use it during home visits. A non-skid surface is essential to prevent birds from slipping, which could lead to injury or skewed weight measurements. Additionally, having appropriate increments of measurement is critical for accurately assessing a bird's weight; this ensures that the readings are precise enough to detect any changes in the bird's health.

In contrast, having a high center of gravity in a scale is not ideal, as it can lead to instability during use. A scale with a high center of gravity makes it more likely to tip over, which can be dangerous for the bird and could also compromise the accuracy of the weight measurement. Therefore, this characteristic does not contribute positively to the overall utility of the scale in avian practices.
