About a year and a half ago i rescued a female puppy from a shelter. Everything is just fine, she loves to run, dig in the backyard, sleep in the sofa, anything simply amuses her.
Once i have a big backyard, when i'm away from home to work i usually let the door open so she can go outside, instead of being closed in the kitchen from 8am to 6pm.
Yet recently she found that she can jump the walls and walk a bit in the fields behind my house. So far so good, there's no predators and no roads for a mile.
When i get home, i play with her, run a bit, "fight" with her and stuff. Immediately after we stop playin, i go inside and she jumps the walls to go after the chickens that are in those fields, chooses one and brings it home. I don't even know if she actually eats part of it or just plays with it. What can i do? Besides building a bigger wall or something.
My dad has chickens too and she just smells them, without hurting ( even were i'm at the window just watching ).
Thank you in advance!
