The biggest deterrent to feather picking is conquering boredom. I probably have the world's worst feather picker. I've noticed when she is free ranging, there's so much going on out in the big world that the only time she picks a feather is when someone stupidly puts her fluff butt under Flo's beak.
When they're back inside the run, I give them jumbo carrots screwed onto eye screws and hung so they swing like tether balls. I do that with apples, too. I fill empty Gator Aid bottles with 1/4 in holes drilled into them with scratch grain and they roll the bottles around for hours to get the seeds out. They've nibbled their flock block down to a softball size lump, so it'll be time to get another one soon.
The main thing is to make them work for the goodies. If all you have for them is layer feed in hanging feeders, you'll have bored chickens.
