I'd ask the dnr to remove it if you think it will start killing your birds.Farmer I worked for as a kid tried this with ground hogs and just about met his end. Got a face full and some in his lungs. I ended up hauling him to the hospital in the farm truck at about 100 mikes an hour.
I like the mink idea.
We either have a bobcat living under our deck or that is part of his regular hunting route. Just starting some new chicks, so I may be on here soon with issues as well. Catch him on the camera every couple of days and wife has seen him a few times.
I’m building a bobcat/coyote/rattlesnake/ cougar/hawk/eagle/rat proof chicken yard. They will be inside a metal shed at night. We have a fenced property which might (probably not) keep the coyotes out but not the others.I'd ask the dnr to remove it if you think it will start killing your birds.
How big is your bobcat?
