I do not understand- I have had chickens for decades and many snakes have lived here and never-ever- hurt any chicken ( I do keep them inside when they are young) For years a 6 foot black snake live in my barn which is attached to my chicken pen. Yes, it will eat the eggs occasionally=BUT I have never heard of a black snake killing a chicken. They eat rodents, eggs, frogs,.
I do not have rats or squirrels that get in my barn or food- guess why???
Black snakes are your FRIEND> they will eat baby Copperheads and Copperhead eggs, they are territorial - I have never seen a Copperhead on my woody property.
I thank my black snake for that.
PLEASE: Do NOT put golf balls or fake eggs in and kill this beneficial creature.
I solved my Black snake eating eggs problem by building a roll away egg box and gluing a fake egg down inside the nesting box for the hens to sit on. I glued it because I did not want the snake to end up in a horrible death.
My husband captures a black snake and relocates it when it becomes a problem. The snake in the photo is the one who lived in my barn - I often cleaned the barn and he watched. My husband finally caught him and relocated him because my dog was too interested in the snake and we were afraid he would bother it.
Please do not kill the black snake!
