A healthy supplement to their natural diet, are blended with honey (not edible glue) and are a great way to get your backyard alive with colour. Even better news is that the seeds are 100% edible, as they have already been de-hulled. This means that the outer husks the birds normally discard before they eat the seed inside, will no longer be left as a mess on your deck or garden. It also means that if they do happen to fall and they arent scooped up by a ground feeding bird, they wont be able to germinate and grow in your garden. They come with a string hanger (made from natural fibres), so you dont need a feeder, just hang from a tree branch and youre away.
