Neither!!! They both have the same mass at 1 kg. However, the feathers will occupy a greater volume.
Lead
The mass of feathers is far greater than the lead. amount = mass So you will have a huge pile of feathers compared to a small chunk of lead to equal a pound
The density of a material is defined as its mass per unit volume. A given volume of lead has more mass than a given volume of feathers. In common usage mass often refers to weight, but that is not a very exact usage of it. For this question it may be useful however to think of a given weight of lead per volume and a given weight of feathers.If you have a kg of lead, that is a small piece, a kg of feathers is a large amount.So for a given volume, say a cubic centimeter, the weight of lead is much more than the weight of feathers.
A pound of feathers because feathers are less dense than lead and therefore take up more volume for the same mass.
The feathers "take up more room" than the lead. It would be hard to compress the feathers to make them as dense as lead. The feathers have more volume.

A pound of lead weighs the same as a pound of feathers. The weight is the same, but the volume of feathers will be much greater than that of lead.
Lead
Although they both weigh the same, the kg of feathers would be much more unwieldy, due to its volume. If the feathers were being carried in an open container, on a windy day, when you reached your destination, you would most likely have many less feathers than when you started!

Something that weighs a ton is equal to other things that weigh a ton, therefore a ton of anything is equal to a ton of anything else. Even if it's feathers versus lead or cotton versus cement.
No, both a kilogram of feathers and a kilogram of lead would weigh the same, as they both have a mass of one kilogram. However, the volume of feathers would be much larger than the volume of lead due to their different densities.

They both weigh the same: 1kg = 1kg. The kg of butter has a greater volume and the kg of lead has a higher density.
One litre of feathers would have far less mass than one litre of lead.
