Factors Affecting Seed Freshness

Many things can affect how fresh seeds stay, but two big ones are temperature and humidity. High temperatures can make seeds lose moisture quickly. This can cause the oils in the seeds to go bad and make them less healthy.

Where you get your seeds is also important. Fresh seeds from good suppliers usually last longer than older seeds or those that weren't stored properly. To keep your seeds fresh, store them in a cool, dry place.
Common Types of Bird Seed and Their Longevity

Different bird seeds last for different lengths of time. How long they last depends on what they're made of and how you store them.
Seed blends, which mix different seeds together, usually stay fresh for 6 to 12 months when kept in a good spot. On the other hand, organic seeds, which come from natural farming, can last up to 18 months if you keep them cool and dry.
A few things can make seeds go bad faster. For example, moisture and air can spoil them. Also, the oils in some seeds, like sunflower and safflower, can turn old and smell bad.
To keep your birds happy and healthy, check your bird food often. Use the oldest seeds first so your feathered friends get the best nutrition. It's a simple way to create a happy feeding time!
