I have found what works best for me, is to leave them alone for the first 2 days.... Then just sit by the brooder where they can see you... After a few days of doing this if possible cut a 2x4 inch hole in the side of the brooder as close to the bottom as possible.... Then, Slowly put your hand in the brooder FROM THE SIDE, with feed in your hand, Dont pick them up just be there... When you do this for a few days, Stick an empty hand in the brooder, They should all hop up, Its ok let them hop up.... Then start to hold them after a few days of this.... The thing I have found to work the best is to NOT make them do anything they dont want to do..... They will come around, The to the point that now my 4 month old RIR, which can be know to be a independent breed, come running up to me, and when i squat down, they hop up onto my lap, on me shoulder, on my head etc, and just sit their....
Hope this helps
