I think if you just want to watch them and don't grab (even if they are fluffy and cute), you could just sit quietly on the floor inside the brooder. You can watch them do their little interesting chickies things and get them used to you. Feed them out of your hand. They will climb on you and check you out. Always move slowly and be quiet around them. When they get bigger, they won't be afraid because they have seen you and you are the food source. This will all take time. As in a couple weeks. Be patient.
