Very, very nice workmanship, congratulations!
Lazy Gardener is right, chicken wire won't protect your birds from predators.
Don't worry about it though, no harm done, leave that on, and just go over it with another layer of half inch hardware cloth.
A 50 foot by 4 foot roll is $61 with free instore pick up at
Walmart, or about the same price with free delivery on
Amazon.
Looks like you understand you'll need an wire skirt around it too. Most people wouldn't use chicken wire for that, not strong enough and will rust out faster than thicker wire. They usually recommend 1"x1" welded wire for the best in ground longevity.
I used half inch hardware cloth, zip tied to cattle panels as the anti-dig mats on my tractor.
You can see the mats in this photo.
I don't know if you get snow where you are, but if you do, put a center beam down the middle of the hoop supported at both ends, to prevent snow from bending your hoop and depressing the shape of your hoop arch.
Oh, one other thing, if you get cold weather, and if it's even possible, put the door end facing north, and leave the other end open wire, facing south.
Zip tie some 8 foot 1x4's on 12 inch centers, cantilevered 3 feet over the south, open end, creating a 3 foot tarp covered eave, that will keep out any blowing rain in the winter, allow in winter sunshine, and give you good ventilation.
Probably too late for that idea though, but either way, you've got a great coop!
You've way more skill than me, I'm impressed!
