Wild bird seed is that which is packaged for birds and their dietary requirements.
So can hamsters eat wild bird seed?
They can eat them as a treat but not as a substitute for their dietary hamster mix.
Many hamster owners will feed seeds such as budgie seed, cockatiel mix, millet and canary seed to their hammies as they have birds as well as a hamster. They should be fine for them, but it should be said that they provide no nutritional value for them
If in doubt don’t feed them wild bird seed as there are better foods for them to eat.
