You soak the bird's nest following the instructions, but after the expected time, the strands are still hard or barely expand. Many people immediately think "it's fake." In fact, there are quite a few normal reasons that make the nest expand slowly; only a few are signs of a real problem. This article helps you check each cause in order and know when to contact the seller. Basic soaking instructions can be viewed at how to correctly soak raw bird's nest.

Common causes (and completely normal)

1. Type of nest and nest thickness

Whole nests, thicker nests, and dried bird's nest generally need to be soaked longer than thin strand or broken nests. See the types of bird's nests.

2. Insufficient soaking time

Soaking time varies depending on the product; follow the manufacturer's instructions. Soaking for less than recommended will result in the nest not fully expanding.

3. Water temperature

Water that is too cold can slow down the expansion. Use room temperature water; do not use water that is too hot as the strands can become mushy.

4. Too little water

Bird's nests need enough water to absorb. Use water that fully covers the nest, several times the weight of the nest.

5. Water quality

Water with impurities or strong chlorine smell can have an effect. Prefer pure water or boiled then cooled water.

6. Very dry or long-stored nests

Very dry nests need to be soaked longer; this does not necessarily mean it is spoiled if it is still within the expiration date and shows no abnormal signs.

When should you be suspicious?

  • If the nest has a sour, foul, or chemical smell after soaking.
  • swiftlets' nests soften very quickly or the water becomes cloudy unusually within a short time.
  • There are mold spots, sticky slime, or abnormal color changes: see identifying spoiled bird's nest.
  • After a reasonable soaking period, if it remains hard as at the beginning and the product's origin is unclear.

Note: expansion is not a definite measure of authenticity. Some counterfeit products also expand; conversely, genuine bird's nests may expand slowly. See misconceptions about bird's nests.

Step-by-step handling

  1. Check the instructions on the packaging again for soaking time and method.
  2. Ensure the nest is fully submerged in water, using clean water at room temperature.
  3. Extend the soaking time slightly and observe; do not soak so long that it becomes mushy.
  4. If it still does not expand and you are suspicious, take a photo, keep the packaging, and contact the seller; see warranty and return policy.
  5. Do not use the nest if there is an unusual smell or signs.
