Pond Boss Forums MANAGING AN EXISTING POND Feeding Fish Feeder Size & Feeder Specific Locations?

I'm looking to add a feeder or two to a new pond. I have a couple general questions I couldn't readily find on the forum. Any tips you guys could provide would be greatly appreciated.

1) What is the shelf life of commercial fish feed? Does commercial fish feed go bad, rot or get moldy if not dispensed within a few weeks of purchasing? I travel a lot for my job and was thinking about getting a larger capacity TH feeder (with solar) to 'load and forget' while away. I'm not sure if fish would notice fresh vs older pellets but wanted to ask.

2) Would it be best to have separate feeder to dispense YOY pellets in the shallows & large predator pellets in open areas of a pond to allow each to feed separately or is it more beneficial to have all the fish congregate together during feedings to allow the larger predator fish to take advantage and feed on the younger fish?

Thanks.
