I’ve been puzzling over my run renovations, and I *might* have come up with a decent idea that wouldn’t require me to rip everything out and spend a lot of money. Pic of current setup so you can picture/critique for me.  (Background info: my run for my larger coop currently consists of a 4ft chainlink fence and that’s it. No roof, no apron, just the fence.  Birds that can/want to fly out have and they free range out to around 100 yards of the coop. We have a lot of sumac to the west and south, and hardwoods to the east, house and yard the dogs stay in are to the north.  We haven’t had very many for-sure predator losses, but last year was pretty awful as some birds flat out went missing, and something tried to dig into my grow out coop.)
My idea is to get some aviary netting and install screw-in hooks just under the eaves of the big coop (on the right) and a 2nd set of hook to the side of the run for my smaller coop (on the left) and stretch the netting across and create a “lid” for that part of the run that I can take down in the winter because we get a LOT of snow in the winter.  Make the fence taller along the front and back sides to secure the aviary netting to, add an apron (of course.)
Other pic is my current small coop run. 2x4 welded wire with a hc apron, chain link on the roof. I’m not opposed to building another one of these, but it would be a significantly larger time and money commitment for the size I would want as there will be around 20 chickens in the big coop and I keep around 8 in the smaller coop.
