As a rule of thumb they can be Josh, but when the water is cold in the early part of the season this changes alot. One such place here I took my kids to a trout tournament just for kids. Parents were helping the smaller ones casting and all..They put in 150 trout in a netted area for them to fish and all in all only 5 trout were caught that day. So yes even stocked trout can prove difficult at times, it all depends on water temps.. There is a set of 3 lakes up here they stock with trout, the biggest is yearly while the 2 smaller ones are done by even and odd numbers of years. Some will tell you how they like to bite while others will tell they wouldn't bite a thing. I like fishing them with a worm laying on the bottom with no movement at all. If any movement it should be as little as possible as trout are feeding on bugs that are not moving much at all, as the water is still very cold for much action.

Be careful about the chumming idea. In some states that is illegal. Plus your lowering the odds of your bait being choosen to be eaten. Try smaller size baits, about the size of a piece of corn, if using powerbait. Definately try different colors of powerbait. Salmon eggs are a must bait to have within your creel. White and yellow are the best colors. Try worms. Not the huge nightcrawlers, smaller ones if available. Hook them through the middle and back through the other side. Use the whole worm. You might need a split shot. I've seen where some people use a needle to inflate the worms to get them off the bottom a few inches. Minnows and meal worms are also good baits. It is just like bass fishing, you need to have multiple types of baits at your disposal to see what they are interested in biteing that day. Don't forget your artificials. Spinners, trout magnets, etc.

Look for skinny water or moving water for trout to lie within. Undercut banks are a great place for trout to hide, plus look for structure. Polarized glasses are a must.

Good luck
