I actually lost close to 20 young chickens this summer too two different skunks. Contrary to much of what I read, I've found them to be deadly to young chickens. They didn't kill any full grown birds but two bantam.
The part that is the craziest is that he was just pilling them up like it was for fun. Many still alive and could barely find the bite marks if at all. Still, the ones that were alive never recovered. They quit growing and wasted away. Two that appeared fine, but first bathed in the heavy spray area that I shoot him in, also wasted away.
So I'm currently in the belief that chickens they may not smell well, but the oils or bacteria from the smallest of birds is extremely toxic. Part of this view is because as a youngster I picked up 3 baby skunks on a 3 wheeler, I did not even realize they had sprayed, and by the time I got home I could barely walk straight. I suppose the smell came on slow enough that I didn't think it was that strong, but my mother didn't agree and I had to let them go. I was so sick though, my love for their cute little faces didn't matter and they went back to the wild!
