You mentioned that you were hoping the chickens would be similar to a dog or cat. That really isn't the case. Birds are a lot different; dogs and cats were domesticated over generations to be companion animals for humans, and birds really haven't been.
You need to get them used to you, and in some cases, assert your superiority over any that are actually vicious toward you. You also need to choose chicken breeds that are known to be less flighty and more docile. Jersey Giants are known to be like that, so you made a good choice there. Just keep posting here at the Chicken Support Group (hee hee) and follow the advice of those who have been there, done that! If you work the lawnchair routine, you'll notice a difference in your flock by fall.
Another thought... Chickens generally see more poorly in the dark; one thing I've done is go into the coop at night (with a flashlight) and talk to and pet my chickens while they were on their roosts (once they were used to me being around).
