Bird seed mix can usually be found in regular pet stores. However, their cost can vary greatly. So, find the cheapest mix your birds will be satisfied with and you can look for the store with the best prices. A good idea would be to learn what manufacturers produce the bird food you need and read some reviews about them. There are some companies out there, which specialize on bird accessories and sell food at the same time. It would not be the greatest idea to buy grain mixes from such a company.

Seed mixes which contain milo bird seed are not the best choice. This one of the least nutritious seeds out there. It usually gets mixed into the bird seed mixes to make them cheaper. Milo seed will produce a lot of mess, since it is often too large for the birds to swallow. If you can afford more expensive mixes, make sure that milo is not one of the ingredients. Milo can be suitable for large wild birds. If you have such birds flying to your yard, then you can leave this seed in a separate feeder for them to eat.
