If you're wanting to use the "grain and mash" method of feeding then naturally scratch grains are important. Presuming you have a feed formulated to go that way of course. Back when I used to use it I mixed whole corn, whole oats, and wheat and fed it in tube feeders. Also used just corn and oats and eventually got it down to just corn. Got away from it when grain prices went through the roof several years ago as it was no longer economically advantageous for me here in Florida.
For the folks who are feeding a typical 15-16% complete layer feed though scratch is not really necessary though it is useful in some circumstances. I still use a little of it myself (whole corn) but not much anymore.
