I did a quick Google search and found that "Humans have around 10,000 taste buds, while chickens have a maximum of only around 350 taste buds. ... And in fact, the taste buds of a chicken are located so far back on the tongue that they have more or less swallowed something before they have any idea about what it tastes like." (www.mypetchicken.com) I see my baby chicks eating sand (as grit) right alongside eating their chick starter. They will also eat bedding, weeds, and other greens I give them. I can't tell if they like something better than the other. So why would you give them something expensive like meal worms? Or even chicken scratch which I hear they also like. But can chickens really taste what they are eating. or is a meal worm the same as eating sand to them? Does the bedding taste the same as their chick starter feed to the birds? And how do they know the worm in the other chick's mouth is better than the one in their mouth, so they have to chase each other and fight about it?
