Reasons for the different sizes of bird's nest
Jin Siyan made the swallow's nest, and each golden silk Yan Dou made the nest according to their own preferences and wishes, so each swallow's shape is different.
Each Jin Siyan has a different nest size because of its different body size and saliva secretion. Whether there is enough food and whether to make a nest for the second time will all affect the size and shape of the bird's nest finally built in Jin Siyan. The amount of feathers and impurities contained in bird's nest is also different, which leads to the different weight of swallow cups after the final cleaning and plucking.
