I have free range chickens who are locked in coop at night. The coop is secure and in the winter it goes in the bank barn for extra security and space. I had a hawk kill my favorite easter egger on Christmas day...she had a tendency to wander from the rooster occasionally though. I am new to chickens but have had some experience in the past with other people's chickens. I have been just getting set up the past couple weeks and need some advice on predator deterrents. On my list is an owl decoy and some ceramic chickens. I now that with free ranging i will occasionally have losses but wanted to see what was available out there that works for some experienced chickeners. A little background as to the terrain. I have about 6acres of land, some wooded and some open and neighboring is a 500 acre park across the street and 2 farms on either side. The chickens mainly stick to the shrubbery and the barn but occasionally graze in the open yard by the barn. I've had them about 2 months and this is the first attack.
