I wouldn't be surprised if it's because there's so much conflicting information. One site says feeding live is okay. Another says feeding live is a horrible thing and that only good owners feed f/t. One will say that paper towels are fine, another will say aspen is the only thing to use. So on and so forth.
I remember when my family first got into goats and we were trying to figure out what green stuff would be best to feed a sick goat. So, we went to google (like so many of you are claiming). We pulled up two websites. One said that oak leaves were good for goats, but poison sumac was bad. The other website said the exact opposite. Both websites had conflicting information. Finally, we gave up. Turns out that neither plant harms goats and in fact, they love to munch on the plants.
Point is, there's hundreds of breeders with their own website. Each one will have a slightly different method, some will be radically different. With this in mind, how is a person supposed to know what is "right"?
