On every website I've read Brahma's and Malines chickens don't fly higher than about 3 feet (1 meter). So thats the hight of my fence. Joséphine was the first to fly over, Charlotte followed. But just 1 time each. About 10 days ago Clara found out how t get out of the run... and since that day I'm always worried. a week ago a friend came to visite, but I wasn't home, she found Clara walking around at the backdoor. So she called me. It's been a daily job to put Clara back in the run. Luckely she always follows me when I call her name and go into the run. This morning I put extra wires on the fence to make in 4 feet high. But 2 houres later I went to check on 'm before work and again she was running around outside the run. I love my animals, but I always seem to have special once who like to break free. I've had the same problem with my rabbits. They are 5 years old now and finally gave up... Does anyone have tips of tricks to keep my chickens inside?? They can't sit on top of the fence, that's just a rope.
