Red mylar ribbons tied here and there. Some fishing line strung on T posts to affect their ability to dive bomb. If you have a fenced in but open top area for the chickens consider a dog on the outside. My dogs love to chase off any bird that lands on the ground.
I was just thinking the other day if a hawk landed on my hen and if I was running and tripped ONTO the hawk and killed it.....would I still get fined for accidentlay killing a hawk??? Not like I would call and ask,but it just occured to me that in the mayhem to resuce my hen I could trip and fall on them both in my bumpy ,hole infested yard!
I agree they are beautiful,but I won't let them eat my hens. Only I can eat the hens!
