I'm not putting a roof on my run!!. It will make them and me feel as if they are confined ALL the time. My chickens have been free ranging for years now. Some stay near the house and their coop, while other travel 100+ yards away, into the woods or pine field. I have only lost a few chickens within 3-4 years while free-ranging. I am more worried about Raccoons, Skunks, Foxes, and Opposums, than Hawks and Owls.
So, thanks for suggesting it. But I do not have to funds for a roof, nor do I want a roof. And like I said, they will be outside the run most of the time, so when their in the run for a few hours by themselves every week or so (On Sundays for church) then I don't think they'll want to try to get out.
Also, I must say. @nellynelly . Are you from Bogota, Colorado. Or Bogota, Columbia?
Animals970, where are you located to not be concerned about aerial predators?
Let me tell you by first hand experience...
I was cleaning my chicken coop and heard the roosters making their aerial warning sounds.
I quickly stepped out of the coop and there was a hawk on the ground right in front of me!
Sharp hooked beak and small beady eyes. It was about the size of a large breed hen.
Luckily it flew off without any of my chickens, but it now knows they are there.
The hawk perches in the trees every now and then a few hundred yards from the coop and run and waits patiently for prey.
Free ranging is taking a risk but they have more hiding places...having a run to confine without a roof is unfair to the chickens, you are setting them up as bait for aerial predators...
the chickens kind of loose their mind when under attack and don't think rationally to go in a coop, running and flying in all directions.
If you have free ranged for years, why change now. Are predators getting them?
There's news that stringing shiny cd's around the top of an open run may help deter aerial predators, if you do not want to put a tarp, netting,fencing, roof on top.
8 feet should suffice to keep non-flighty birds retained.
