100 pounds of bricks occupy very less area compared to feathers. Thus, you apply much greater force to lift the box of feathers compared to bricks. Due to the larger force you can lift the box of feathers easily which makes you think that it is lighter.
Answer: They both weigh the same (100 pounds).
Great question, but you could find the answer through some very quick googling. So from some googling I found out that 1 feather, on average, weighs roughly 1 gram. 1 pound is about 0.454 kilo grams, or about 454 grams. That means that we can fit roughly 454 feathers in 1 pound of feathers.
If measured on the surface of the earth, the kilogram of steel weighs more. Just very slightly. Steel is denser than feathers and hence the buoyancy of the feathers in air would reduce the resulting weight.
Technically, the pound is a unit of mass*. So, for standard weighing conditions in air, the weight of the air will provide more buoyancy for feathers than for bricks, so the pound (mass) of bricks will indeed weigh heavier than the pound (mass) of feathers.
"Which weighs more--a pound of lead or a pound of feathers?" The seemingly naive answer to the familiar riddle is the pound of lead. The correct answer, of course, is that they weigh the same amount.
In the Troy system only 12 ounces equal a pound. So a pound of feathers weighs 453.59 grams approximately and a pound of gold weighs 373.24 approximately. So a pound of feathers weighs more then a pound of gold. Some say gold because it is heavier.
0082 grams. This means you'd need about 121,951 feathers. So you could try to picture 121,951 feathers and stop there but if you'd like further visual aid the average chicken has 9,000 feathers this means to get a kilogram of feathers you'd have to pluck 13 and a half chickens.
Argentavis. Argentavis magnificens was among the largest flying birds ever to exist, quite possibly surpassed in wingspan only by Pelagornis sandersi, which was described in 2014.
Yes, you can actually ride them and survive - ostriches, not New York City subway trains. And what better place to learn than Oudtshoorn, the ostrich capital of the world?
1 pound is about 0.454 kilo grams, or about 454 grams. That means that we can fit roughly 454 feathers in 1 pound of feathers. This is, of course, not very accurate, since feathers' weighs varies depending on size and what bird it came from.

They will be decently painful, but usually won't get the kind of piercing wounds you might get from a dog or, God forbid, human bite. When it comes to big bois like ostriches and emus, its the kick you have to worry about.
But for animal rights groups like PETA, even this painstaking method of collecting molted feathers is inherently inhumane. Unlike other birds, ostriches — prized by the fashion industry because of their lush, luxurious feathers and versatility in that they can be dyed any color — don't molt.
Common household items that weigh approximately 1 gram include a paper clip, the cap of a ballpoint pen, a stick of gum, a U.S. bill of any denomination, one-quarter teaspoon of sugar, a raisin and a thumbtack. The gram is a metric measurement of mass that is equal to 0.001 kilogram.
Ostriches appear to sleep out in the open with other members of their herd.
An ostrich makes a variety of sounds, including whistles, hoots, hisses, growls, and deep booming growls that sound like the roar of a lion.
On average, a feather weighs just 0.000289 ounces (0.0082 grams). That's really light! Ornithologists frequently study birds and their feathers. The number of feathers on a bird is calculated as a proportion of their body weight.
Argentavis magnificens is a large bird that was discovered in Argentina by avian paleontologists Campbell & Tonni and was given the name Argentavis – a name which means “Argentine bird.” It is believed that these birds occupied the skies over South America during the Late Miocene Period, about 6 million years ago.
Even the largest North American birds—such as the bald eagle, the golden eagle, and the great horned owl—don't commonly attack humans, and can't lift much more than a few pounds.
