Black Skimmer Tagged Q6 in Wrong Scrape

When I first started checking on 6Q’s scrape, he and his mate had 1 chick and 3 eggs. Then he was down to just one small chick, and I shot some good video of the cute little guy two days ago. Yesterday, Wednesday, when I checked on his scrape it was empty. I looked around and found a scrape close by that had a small chick in it, so I focused one of my cameras on it and let it record. It turned out that it was 6Q’s mate and chick in that scrape. But then she left. The chick was left alone for almost 9 minutes and 8K wanted the chick out of the scrape. Finally, 6Q returned to feed the chick and moved to another scrape. A short time later, Mom returned with another fish for the chick. Did 6Q’s mate and chick move to 8K’s scrape?
