When I was a kid, I set up a drop net. It was just a loose net, nailed to a lightweight wooden frame, and propped up with a stick like a lean-to, with a string tied to the bottom of the stick.
I fed the chickens in there for a couple of days, until they were waiting for me under the net when I went out to feed them. I fed them one more time at the very back of the lean-to net, then I walked away so the shy ones would crowd in, and I pulled the string.
It worked! I was so surprised! My dad was very proud, and he helped me get the chickens penned up.
I think I remember it so well because that kind of success is so rare!
I have a big fishing net i use. Some of my birds when i let them in lower part of yard don't want to go in even right before dark when they see net they run in coop just wait till they jump in the air put net under them as they come down and u have them.
