Federal officials plan to shoot darts filled with liquid birth control chemicals into mares as part of a plan to control the growth of the wild horse herd in the McCullough Peaks, about 20 miles east of Cody. The Northern Wyoming Daily News Worland reports Bureau of Land Management officials are accepting public comments on the plan through Feb. 22.
Darts would be delivered through an air gun by horse specialists riding four-wheel drive vehicles. Horses that can’t be shot with the darts from between 30 and 50 meters will be given the chemicals through bait trapping. BLM officials hope to maintain the herd at between 70 and 140 horses through 2015 by targeting mares a year and older for birth control.
