He should be good for a little longer. The trouble is judging it if you do help. A couple that we helped still had active veins going around so all we could do was give them a little air where it had dried up until they were ready to do the rest. It seems where the air sac was dries Ou first. I helped 4 out of 5 of mine. 2 we accidentally hit veins and bled a little but they are all the noisiest healthiest birds around! I'd go with your gut instinct if you have one.
