Some chickens can be tamed. Others cannot.
For thousands of years of domestication, they have been bred as
livestock, not pets, with the focus on producing meat and eggs, not on cuddling with humans.
Our most common cuddle-pets, cats and dogs, are PREDATORS, not PREY.
A predator can be more comfortable being handled because in the back of it's mind in the deepest level of instinct it knows that if you hurt it it can hurt you back -- or kill you and eat you.
A prey animal's instincts are completely different. They do not fight. They run and hide. To be caught and held is to die. You can't change their nature.
I do not have hundreds of chickens' worth of experience that some people do. I have had 24, in two different flocks.
Of those 24 chickens only 2 liked to be picked up and petted and one more didn't mind -- until he matured, at which point I judged that a rooster should not be a cuddle-toy and was content that he respected me and didn't become aggressive when I handed his hens.
One of the ones who actually liked to be picked up was a cockerel who went to freezer camp at 4 months old.
The other was a hen who remained tame and friendly until she first went broody. She was a fierce and determined broody who, lacking fear of humans, bit HARD in defense of her eggs. After she was no longer broody she was also no longer interested in being handled.
You cannot realistically expect a chicken to be a feathered dog.
Instead of focusing on wanting to hold them and pet them, try learning to enjoy them for what they actually are as
chickens.
