Danielle, try not to be fearful of your chickens. It's easy to misread their actions until you get to know and understand them. I believe you will soon come to see your chickens as the very lovable, gentle little creatures they are.
Most chickens, when released from a protracted confinement as yours were for five days, act as exuberant children being let out for recess. Young pullets will actually fly, and it's often accompanied by quite frightful sounding screeching. The older ones will run out and race about, especially if there are wonderful garden things to explore.
I suggest you lay out a blanket, plant yourself in the middle of it, get comfortable, and wait for your chickens to wander up and get to know you. It would help speed up the process if you had some raisins or grapes, or some grated carrots. Whatever treat you wish to share with the chickens, place beforehand in a convenient container that you can use every time you do this. Very soon, the chickens will associate the container with treats, and will come to you whenever they see it. It's a super handy method of rounding them up and getting them back into their run when you need to.
You'll quickly learn your chickens each have a unique personality, and very soon one or two may even decide you are their new best friend.
