Joe: apologies for jumping in on your thread but I have been dealing with this exact problem.
My male coopers is about the same age as yours, yesterday was day 8 of hack. Yesterday he was an hour and a half late for the afternoon feeding time so I had to track him down. He was very nervous, in fact the first time he came to the lure he landed about 15 feet away and flew back up to the tree. He finally came back down and once he started eating I was able to walk up and clip onto his jesses. This was the first time he has shown any fear, my guess is the bottle rockets had him spooked but I'm not sure. Just to be safe he is staying inside today for lots of socialization. Haven't decided yet if he is going back outside tomorrow or if I am going to continue as a traditional eyas, with extra baggies and walking fields once he penns.
For comparison he was 15 days old when I took him from the nest, and the 4th dark tail band is just coming out of the tubes now.
