From Sheep to Nest...... Birds will enjoy pulling tufts of our sheep's wool from this decorative suet feeder to build a cozy nest. The soft wool provides a warm place for adult birds to rest and a cushion for their eggs. To use, hang the wool filled suet feeder on a shepherd's hook, in a tree, or near your bird feeder. Each suet feeder is filled with babydoll sheep wool from our flock at 1818 Farms. The wool is hand washed using an all-natural plant based cleaner. The wool is carefully hand carded and dye free. You may notice some vegetation in the wool. This is a natural occurrence and is perfectly safe for birds to use. After the initial use, the decorative metal suet cage can be refilled with wool or used as a feeder. Each suet feeder contains 18 grams of wool. Suet Feeder Dimensions - 6 1/4“ H x 5 1/2" W x 2 1/2" D
