That's not how it works. If you want "organic" chicken, then yes, you will want to feed "organic" feed. However, the point of feeding organic is to avoid any residue of pesticides or herbicides that have been used on the plants that make up the feed. For instance, some genetically modified plants have been designed to be resistant to roundup, so that farmers can control weeds easily by spraying roundup over the entire field, thus killing everything except the crop.So, if you have feed that, for example, contains corn that has been sprayed with roundup, the supposition is that the feed may contain residue from roundup, thus getting that into the meat or eggs. Eating GMO corn does not change the genetic makeup of the chicken, that sort of thing happens in the laboratory only. However, once an organism has had it's genes modified, those "new" genes are then passed on to it's offspring.
