No Fire.
But I have a new thing for you to check out.
Birds can detect UV reflected light.
I have a large picture window that I try to keep birds from hitting. It is near our main bird feeder. The best thing that I found was to put a grid of bright yellow marker on the outside, It glows like the dickens under UV light and you can see the birds veer away from it as they approach.
You have chickens---so—an experiment may be in order.
“Doctor (does it glow) Fire” and a new experiment in the making. I think that it worth a shot.
Just sayin,
Marble—On!!
