Love your question. I am in a similar environment. We have lots of wild turkeys in the area, some stay to visit for a while, others pass thru every 4 days.
THese woods are open and easy to walk thru, you can see for 100-200 feet around as far as spotting predators. I do see my roosters on guard, they seem to keep watch more than the chicken hens.
Ond day this fall, the entire flock screamed the alert and raced for home. I thought, false alarm, then the notion dawned "maybe not". I ran thru the oncoming birds to the woods and I looked. THey he moved-- a coyote. WIthin 100 feet of the house. He turned and ran. Pretty coyote.
Deterents work well with coyote-- they will go for the easiest food, so I make my critters hard to get. I use various wire mesh fencing to surround the main area. THe coyote follow the fenceline and stay out. THis particular red coyote came in where there is NO fencing.
Go to the ALBC site for some fencing ideas-- there is no ONE right solution. THey rightfully state that each type of fencing has pros and cons. It offers more details than I have seen generally.
THey coyote do not enter my horse paddocks or the sheep pens. I"m thinking out a new layout to put the larger livestock further out-- I don't think a coyote will try for a 300 pound ram.
Good fencing!!
My birds do not forage as I thought they would. S and S Poultry confirmed that they are sight feeders, not scratch and eat feeders, so putting out feed will be 100% necessary IMO. I do see my birds eating grass, so my back yard is getting very short right now. TIme to move them off that area to save the grass.
I hope this helps-- I"m still learning about poultry, not a lot of experience.
