HELP! My wife and I are new to keeping chickens. We currently have 7 chickens, but started with 10. We have had them for about 3 months now. I have a very nice chicken house that is under the lean-to on one side of my shop which is further enclosed by a 4' fence/run approximately 24'X15' under the lean-to. We started with a 160' long net fence as a run that was attached to the chicken run from corner to opposite corner stretching into the side yard, but we decided we wanted to truly free range them so we took the fence down about a month ago now. They love it as you can imagine. Around the immediate area were is about 4 acres of cleared property that the house and shop sit on with about 20 acres of wooded area around that. A couple of weeks ago 2 of our girls decided not to return for the night. Despite 2 hours of searching in the dark with flashlights in the woods we were unsuccessful. The following day 1 returned. She immediately went broody and we thought at first she was traumatized due to possibly dealing with a predator that may have taken the other hen since she never returned. So at that point we lost 1. Now today I have lost 1 for sure and possibly a second. We found a lot of feathers and one of the girls with flies already on her in the woods on the backside of the house. She's in heavy briar's and can barely see her, so I am unsure what got her. Not sure where the other is but it does not look good. We accounted for the other 7 and we have penned them back up and we have placed the net fence back up and will discontinue the "open" free ranging and go with the pasture free ranging instead. At least that way we can control their movements. My question is: should I put some sort of cover over the top of the net fence to give that much protection, or will having it connected to the chicken coop be sufficient for them to run for cover?
