The Kaytee Finch Station 2 makes attracting and feeding finches easier than ever as they adore soft mesh socks and prefer them over traditional tube feeders. The unique, Squiggle Sock design provides more surface area that enables finches to perch wherever they want, and allows for numerous birds to eat at one time. The weather-resistant dome reservoir which holds extra seed, automatically keeps the sock filled longer. Each feeder comes with one sock for initial use and one for replacement. Feeder holds 3.5 lbs. of food. Mesh socks are refillable and measure 18".
