With the Kaytee finch sock feeders, you'll have no problem attracting and feeding your backyard finches. This feeder was made just for them and it features the soft mesh sock they prefer over tube feeders. The unique design provides multiple perching options and allows several birds to eat at the same time. It includes two socks that are already filled with premium Kaytee Nyjer seed, so you can hang them in different areas of the yard or keep one as a backup.
