hi, as it happens - I spent several hours at the chicken run yesterday doing a little gardening.
My run has 2" square welded wire walls so my girls can reach right through and eat anything within about 6".
(although I swear that silky can get her neck to extend about 10", ok, not really but it sure looks like it!)
Well, I wanted little rows of flowers along three sides of the run, right up against the wire walls, but knew they would eat any seeds they could reach and MOW all of the sprouts as they came up. So, I cut 15" strips of 4' chicken wire off of the roll (abt 1" holes), and from the inside of the run I fastened them along the bottom edge of the wall. I used the cut sides to fasten by bending the cut parts with my fingers out/up/down. My fingers got poked and ache today but that passes (how we suffer for our girls!).
Then I cultivated 12" wide beds along the run and planted: white malva (a hollyhock relative), mixed yellow/orange marigolds, carrots, and 2 kinds of sunflowers.
I'm not planning to EAT carrots that grew so close to chicken poo - but I love their feathery foliage and later this summer I will give them to the flock.
Some very nice person had a post on here about their chicken salad bar - with amazing photos - and I plan to make a small one for them real soon.
Happy gardening!
