I had a brainstorm about using flyscreen mesh over the top of the hardware cloth on my new coop/run. Is this a dumb idea? I realise the flies will still come in when the door gets opened, but I figure the chooks will soon get rid of those and I'll have sand/DE in teh run anyway. Was hoping to find a way to avoid walking through a sea of flies in this heat - they seem to go for the poop as well as any food scraps on the ground. There's got to be a reason no else has done this.
