I wouldn't say stupid. They have a different intelligence capacity or bar for their knowledge limit. When looked in animalian contect, they are quite average. Some may be lesser than others, but you cant compare your view of "smart/stupid" and judge them directly. They are of course much lower on the food chain.
My babies are smart. My normal male just finished 2nd grade.
lol, ok ok. I guess you're right in that aspect. It actually is amazing they know how to eat right out of the shell. That's pretty sweet to be honest.
