Hmm, I was certain everyone's would act the same. Mine really bacame noticeable about day 3-4. I usually added the powdered food, and then the rots right after (probably 1 minute or less while they were still searching frantically for the source of the smell). When I really noticed it, was after rinsing the rotifers, I literally poured the rots out of the collector into the tank, it was only 7-8 drops, but it probably contained 300 rotifers. These all stayed together in the flow for quite some time. If I add food first, they swarm to the rotifer ball and eat like crazy. If I do not, they just wait until a rot happens to drift by, and eat it then.
I also visually saw them eating dry food on day 5, which is pretty early if I'm not mistaken? I only fed BBS for 3 days, in addition to dry food. If you can believe this, there are probably 15-20 brine shrimp that are maturing in there with them, so they didn't even eat all of the BBS. When I switched to dry food only, morning of day 8, I lost about 10 over the next few days, it's now day 10 and all is well. I have well over 100 left, with probably 20% showing headbands.
I don't have enough experience to know if the metamorphosis timing is right or not, but I know their activity level and survival rate is WAY up for day 10, especially when compared to my previous two hatches. Maybe I'm just caring for them better, and looking for reasons why they aren't all dead
