Hi, We have guinea fowl and yes coyotes too. Have watched the coyotes chase them all over ,even up in the window sills. Guineas always shoot first and ask questions later so to speak. They sound off at any thing suspicous or different. The only thing guineas like better than themselves is a mirror so they can look at themselves. A friend wants to record them for calling also. But I'm not so sure the coyotes will respond to their distress since they sound off all the time. I think they may respond to a recording of them talking or calling when they get seperated. The coyotes generally get after them just after leaving the roost at daylight or when the guineas are sunning miday. We have caught the coyotes sleeping under the pen or roost tree even in a foot of snow. They(birds) do eat good when young(no tendons) but can get chewy when older or cooked wrong.
