So I went back out and looked more carefully. I think that there are some feathers of intermediate length that are filling in the gaps. In the above pictures I tried to hold the coverts back and show the feathers I'm taking about. In the last picture my index finger is directly on them. I'm hoping I just caught this guy in mid molt and he'll be OK. I had ten cockerels and kept only him. Wishing I had an insurance cockerel now. I went back and looked at some notes from earlier this year. Next to this guy I mentioned that he had "good wings". So this adds to my hope. Thank you all for your comments and help.
