Any engineers out there?

I need to span my 60' chicken pen to hang netting or wire, to keep out hawks and owls.

I'm thinking to make trusses with 3/8" rebar. Two straight on bottom, with a single curved on top. Triangulated supports every foot, bottom pieces parallel at 6", top curve 6" at center. Hopefully I described it well enough.

Thing is, on a 60' span, is it going to hold up some netting/wire, let alone collapse from its own weight. I've calculated the weight @ 72lb per truss.
