I did the same to one of mine. A pretty border collie bitch. I feel bad now because my neighbor came over and told me she was killing his chickens and I basically called him a liar in so many other words. Then…
I started noticing my chickens …as in 2, 3 even 4 started coming up missing. And laying around dead so I started watching her but could not catch her. Next part is true but hard to believe. One day I was sick and stayed home and my kids who were teens got in the car and drove to school (normally I drove them)and I just stood in the window behind curtains and watched . The dog lay there innocently and when the car left the drive and was out of sight she waited a sec then trotted to the chicken coop!!!
By the time I got dressed and walked out there she had already dug a fresh hole under the wire and had killed 2..she saw me and immediately SPRINTED away to a woods and didn’t return until dinner time.
I didn’t kill her immediately tried to train , even the old trick about hanging a dead bird from her neck. Nothing worked…it’s a blood lust.
So a few weeks later did the deed. Hurt my sons feelings as he really liked her but I won’t keep a pet killing dog around especially when it thirsts for blood so much it raids neighbors houses.
High intelligence in dogs can be used for bad things.
And, therein lies the problem.
You bought a working breed because it looked 'pretty' but didn't give a job to do.
So, it found a job it enjoyed -- killing chickens.
Working breeds need to be 'working' every day. Otherwise their excess energy causes bad behavior.
If you want a dog that just lays around all day, adopt a greyhound.
