I had the same problem. One day about noon i looked outside and saw something behind a fencepost about 10 yd from the back porch. I didn't think anything about it, because I thought it was a chicken until I saw it's ears. Me (I'm 13) and my dad grabbed our guns but it was to late. He was gone with half of one of our barred rocks and our dark cornish was missing. I was mad because the Cornish that was missing was one of my favorites, so I downloaded a chicken distress call and burned it to a cd. I played that forever and it didn't come back up. That night when I put the chickens up, I heard some leaves crunching, and my dark Cornish (her name is Eva) came running out of a brush pile. My mom went out to look in the brush pile and there was 17 eggs in there. Fast forward about a week and one morning about 5:00 AM our dog started barking like crazy, and my dad went out there because I was asleep and shot the coyote. There were 2 of them but he only got 1. We haven't had anymore problems, but we did get rid of the dog because she killed our white rock roo, and we got an English Shepard. He is only like 3 months old and the entire time since we killed that coyote we didn't have any more problems, until last night when our pup started barking and we went outside and there were a few coyotes. So if you want to get rid of the coyote problem you should have a good dog and a gun.
