Adding Weight

There are four deceiving practices you need to know before you buy a bird’s nest from anybody else:

Adding weight by adding water: To avoid the bird’s nests becoming brittle and crushed during the transportation, they should contain between 5% and 10% water. Some companies are known to add more than 15% of water to the birds’ nests in order to increase their profits.  However, the higher moisture content makes the nests turn moldy faster and requires them to coat the nests with spray glue, similar to hairspray, to preserve them.
