One thing that has helped me to catch chickens is that since they were baby chicks, I picked them up and carried them a little on a regular basis - holding them close and supporting them as you would carry a small animal, so they get used to being picked up.
The other 5 come running when I clap my hands and call "Come on Chicks!"...but I think one of the Isa Browns actually likes to be picked up, and when I call them to get in the coop after free-ranging a bit, she'll get about 10 feet from the door, refusing to budge, and just stand there looking at me....waiting for me to come pick her up and put her in the coop! Perhaps just a little.... "spoiled?" It actually makes me laugh every time she does that....
But I am glad it wasn't a challenge to catch them today as we have about a foot and a half of snow today, and it is going to be 22 degrees BELOW ZERO with strong winds. I debated about this, because they do have a fairly draft free coop.....but that just seemed to cold for any animal if it didn't have to be, if there was an alternative. So I set up a big dog cage in the mudroom and carried them all in for the day/night today...and was really glad I didn't have to chase them all over the place in this freezing cold weather!
