I am a gardener for a beautiful event center. We have about 15 free range chickens on our grounds whom I find quite wonderful. The problem is, they are eating our flowers. Has any one trained Chickens to not go into certain areas without a fence? (I goggled this and saw someone had used a broom - but not sure if this would be a long term thing) We would love to have harmony between the plants and the birds! any advice would be greatly appreciated!
