I can no longer view this Cam at work, but I checked on the Bird Cams Around the World site to see what is happened here. The postings there indicate that everyone was worried about Dot and the way she was treating the chicks, but eventually she figured out what to do when the chicks crawled towards her, and she fed them, even though it wasn't clear whether she was feeding them or pecking at them. As of this morning, though, she seems to have figured it all out, and the site says that all the chicks are alive and have been fed. As for Dad, no one seems to know if this is original dad or a new dad.
