Forgot to add it will all be surrounded by 100' of electric netting
I am very happy with my electric netting from Premier 1. I got the 48" and so far any escapes over the top have been accidental cases of catching unexpected air.
I did have to put some 18" plastic garden netting inside it to make it chick-tight. Up until 6-8 weeks they could scoot right through (or, in the case of a determined Wyandotte, dig under).
