X-Tuff Single Sided Hay FeederThis very strong X Tuff Feeder stands up to abuse from big sheep, horned goats and years of hard use. Everyone is impressed when they see these. Heavy enough to keep your large ewes from knocking it down like similar plastic feeders. Small openings (2 1 2" x 4 1 2") prevent sheep and goats from pulling out more than they can chew. Holes on the bottom of the hay feeder allow lambs kids to eat. Specs: 18" tall 18"21 1 2" wide 6 1 2"10 1 2" deep 3 16"
