Here is a quick update.
All the ice on the pond is fully melted, and I have started to feed floating pellets. I see feeding activity only when I feed around 30 minutes or less before sunset. Feeding mid afternoon did not result in any trout surfacing. I have only been feeding about 1/4 - 1/2 lbs of food a day, because I am not sure if all of it is getting eaten or not. I caught two trout in 10 minutes of fishing two days ago, and they were both fairly fat looking, so whatever they are eating, they are eating well.
I ran a castable camera setup through a day ago as well, and caught two fish on camera briefly. Here is the link to the video for those interested: https://youtu.be/NrgMmG3OCzw
