Lightweight, long-lasting poly chain collars in six bright colors, each with a flexible connecting link. Sturdy and comfortable to handle. Colors let you "mark" goats for individual care: How much grain a doe should receive, which does are milking, who should be bred, etc. Chain is not strong enough for tethering but adequate for temporary tie-ups. Links tend to break if goat gets tangled -- a safety feature for goats grazing in brush. Not as big as cattle chain. 1-1/2" by 3/4" size link. Each collar is 20" long with connecting link. Plastic chain collars come in red, green, yellow, white, blue, and black. Discount for buying 10 or more collars.
