Pointers on helping my chickens be more comfortable with me.

first and foremost - I am eternally grateful to this SR!

My chickens are scared of people. I'm just looking for ways to make them more comfortable with me. they were only held as chicks, confined to a small, inappropriate space before I received them. I had to give away one rooster. so I need some sage chicken advice!

here's what I'm doing:

-I am very calm around my chickens

-When I let them out in the morning I very softly say good morning, like I used to do when my kids are babies.

-I will sit next to their run, while I eat or at least 5-30mins a day.

-I give them treats.

-I gently pet them when I close them up for the night, until I can see it bothering them, and stop.

I don't want to just pick one up and hold it, because I feel like that would be traumatic.

so any suggestions are welcome!
