I know I'm only 11 but I still care about chickens
Aw.
Oh to be that sweet again.
My 2 youngest are 13 & 6. They want to hold the chickens too.
But....chickens are born with an innate fear of being held because that's what predators do.
If you chase them down to catch them you're acting like a predator.
Trust will be gained if you temper your love with patience.
There are lots of good ideas in this forum.
Different ways work for different people.
Most probably you'll find your own way by trying a few different ways.
Lots of good ideas here.
Good luck
