My happiest chickens that I have had yet are 11 young'uns that were raised by a broody all by herself.
Most of them, I have never even touched. These chicks are definitely quite like wild ones, they run and fly and if you try to pick one up (which I had to do last night, as it was sleeping in a tree) they sound like a wild animal.
I leave them be, and they are so healthy and happy looking.
