You have come to this page because your current feeding regime enables you to supplement through a suitable "carrier" food sometimes but not every day. You will need to decide whether to change your feeding programme to incorporate carrier foods everyday (our preferred option), to use an on-food system some days and an in-water system on others or to compromise and give your birds supplements only on a few days.

Read the page that describes the benefits of on-food supplements over in-water supplements and then decide what you are going to do. Many bird keepers chose the in-water option for non-breeding birds and switch to on-food supplements before and during the breeding season.

The options for supplementing on the food are described here. The in-water options are described here.
