Some of my chickens, I could catch just by picking them up or bribing with some treats. Others... not so much. When we decided to sell five of our older chickens to make room for new chicks, I had quite an adventure on my hands. Obviously, I had no intention of selling my friendliest chickens. Those were my girls, my pals. Besides which, the buyers lived out in the country, and needed chickens with stronger survival instincts if they were going to have a chance.
You know the problem with chickens who have strong survival instincts? They're hard to catch.
I was chasing hens in and out of a cedar hedge for about fifteen minutes. Finally, I got them flushed out and into the open where I could net them, but not before running myself ragged. Fortunately, I only had to chase down a couple that way--the other three were still in the run at the time and I was able to close them up and corner them.
