My Chao in SA2:B will eat like it's starving everytime I give it a tree fruit. It won't eat all of one, and it will never eat like if it wasn't starving. I took him to the Chao Doctor and he's fine. What's wrong with it?
Some chao just eat more than others. It's nothing important so long as they're not being starved (in which case they might run after you, arms outstretched, if you're holding food). Check its personality type with the Chao Docter; some chao are classified as being "Big Eaters".
