Life, is a Learning curve.
Thats a great idea. I use a 50x100 foot Deer net over mine. I was lucky and bought it at Walmart on end of year clearance sale for 7 bucks.You could try a net or just stringing yarn/string/ribbon in a criss-cross fashion to deter the aerial predators. Even some big potted plants (fake or real) to obscure the runway/landing pad for a hawk and give some cover to the chicks. You might be able to find these items free/cheap at goodwill or on neighbors curb after a garage sale or on craigslist. Hope you can build your hoop coop soon!
I often see the netting at my local Thrift Stores also. That was a great idea to offer.
