Welcome to the forum Timberframe, you didn't mention if you have any forage fish in with the trout.
100 trout should be no problem for your pond even if they are fairly large, how big are they?
Aeration can have alot of variables but when the pond is near freezing over I run the aerator non stop thru the winter in about 4ft. of water to keep an area open for air exchange and running it shallow reduces the chance of cooling the deeper water too much.
Many people on the forum use well water for their pond and usually run it over some structure to aerate it before entering the pond.
I have Golden shiners and Pumpkinseeds in the pond with my trout and they supply extra food for the trout. If you decide to add supplemental feed just use enough that they will use in about 15 minutes. If you have plenty of natural forage they may not eat much of the pellets.
As Cecil mentioned Brook trout are more sensitive to low O2 and warmer temps., Good luck and keep us updated.
