Summarize the following:
Bird netting materials can prevent owls from getting into your chicken coop. Netting is typically placed over structural openings on your coop and can be attached with bird netting mounting clips. You can also use a tarp sheet if you want to give your chickens some shade. Local hardware or garden stores should stock all of these materials. Be sure to get some measurements from your coop so that you purchase something that is big enough. Use orange netting if possible, as both owls and hawks see this color well. Larger coops usually provide adequate protection for your chickens, making netting unnecessary. Areas with plenty of bushes and shrubs can provide natural cover from predatory birds like owls and make it more difficult for them to attack. If you plant your own ground cover plants, make sure they are varieties that chickens can eat like lavender, rosemary, sage, wormwood, fennel, thyme, nasturtium, and comfrey. Double-check that they are suited to your climate zone. Purchase pH papers online to check if your soil matches optimal pH levels. If it's outside of the recommended range of the plant you're going to grow, use an appropriate adjustment technique. Ground cover also provides shade for your chickens during the hot summer months. Prune branches and remove any trees that make ideal perching spots. Before you conduct any removal services, make sure that any tree or structure you're removing is on your property. Hire an arborist for anything you are uncomfortable doing on your own. If there are trees on neighboring property that are giving you owl problems, discuss the possibility of removal with your neighbor before taking any action. Roosting spike strips have vertically-positioned spikes that make it impossible for owls and birds to land on them. Owls typically perch in high spots to observe your chickens and plan their method of attack. Take note of any regions that could be used for roosting in proximity of your chicken coop and place roosting spikes on them, such as near rain gutters. Roosting spikes can be purchased online or at local home hardware stores, and are also called "pigeon spikes." Use non-silicone-based outdoor construction glue to apply spikes to steel. You'll need at least 4 number #8 wood screws for every 0.61 m (2-foot) section of spikes installed. with at least 15.24 metres (50.0ft) between each post. For free range chickens, electric fences are fairly cheap and not too tough to install. Although they are more effective for defending from ground prey, these fences can also prevent owls from attacking. You can attach electric fences to pole shockers, which can prevent owls from perching on any poles close to your chickens.
Cover your chicken coop with protective material. Raise your chickens in regions with ample ground cover. Remove perching sites within 91 metres (299ft) of your chickens. Place roosting spikes on perching areas 91 metres (299ft) past your coop. Install an electric fence
