Hi yall, how high do you think a fenced in run should be that has no top. I want to let the ladies into a new area of untouched grass but I do have coyotes. So I was thinking during the day, when I'm working outside, they could free range into this area, but I dont want to fully enclose it. I was thinking a fenced in area so they don't wander into the woods, but how high does a fence need to be for a chicken to recognize it as a barrier. I have an Ameraucana, 4 Polish, and a large orpington, if that helps. Yes they all fly i realize that.
