Why weigh your bird?
Birds hide illness, and weight loss is often the very first sign something is wrong — long before you would notice anything else. Weighing weekly on a gram scale, and writing it down, lets you catch problems early.
How to weigh a bird
Use a digital scale that reads in grams, ideally with a perch on top. Weigh at the same time of day (mornings, before the first big meal, are best). What matters most is the trend, not one reading.
