I just got goslings (I have chickens, too), and goslings are eager to go out and graze. They are too small to intimidate anything at the moment.
What I did was get an old trampoline and put a wire skirt around that. The tramp surface protects them from any overhead dangers, and the wire skirt keeps ground level dangers at bay. I don’t leave them out there a long time, but I can leave them out there as I do other things in the yard.
I can move this around the property easily. You could do the same with a 10X10 “easy up” canopy. I think it’s a reasonable compromise.
My chickens have a coop, a small 12 x 18 wired pen, inside an approx 40X60 pen, inside the yard which is fully fenced (but old, and probably has gaps.) We have lost 2 chickens to fox, but we plugged that hole last year and haven’t had a problem with them since. Earlier than the fox, I lost a young chicken to a hawk. Most of the others were smart enough to hide under bushes when the hawks are out.
I have way more eggs than I can use. 7 chickens, 2 of which don’t lay.
