How much do a feather weigh in oz or lb?

A single feather can vary significantly in weight depending on the type of bird it comes from. Feathers from hummingbirds may only weigh a few milligrams, while feathers from larger birds like eagles or turkeys can weigh several grams. In terms of ounces or pounds, it's not common to measure the weight of individual feathers in these units as they are very lightweight. For reference, there are 28.35 grams in an ounce.
