Only two had health issues the very first one was missing a foot. And one last year had a mangy tail. The rest were healthy. I bait with a beaver leg and if they are dried out from hanging in the cage for a few weeks that seems to be when I catch the Coyotes. Coyotes frequently enter cages and trip the doors but the door it’s them on the back because the Trap is too short and they just back out before the door closes. Longer traps could be more successful. But I have caught them in small 16 x 16 42 inch long have a heart and little giant traps
