Chickens are highly wired to escape when in danger, it's been like this since they were in the jungle, it's embedded in their genes. Their instincts make them fly away when we try to hold them. I sit in a chair and wait for them to come to me, they sit in my lap, preen and nap but I never touch them because they will run away. I have learned to enjoy their company just by having them on my lap or shoulder. It is still very nice without having to pet them
