Recently i purchased a 35 dollar basket of trailing petunias, 2 hours later they have been reduced to stems! I am planting a garden this year and am concerned that my hens will destroy it. can i electrify my fence or will that harm them? What can I do? I keep my hens free range because their main purpose is to eat the ticks and scorpions in my yard. And they do a fabulous job. They are great layers too! Any Advice?
