So I got some walnuts and since my lovebird Jojo has never tried them I decided to let him try one. He is obviously too small to break a large walnut so I cracked one for him and offered him a piece. He tasted it with his tongue and didn't like it, but when I took off the bitter brown skin that covers and tried the white/yellow inside with his tongue he went all over it. However, he didn't bite any chunk out, more like he was trying but couldn't. I never noticed cause he normally eats an apple or steamed broccoli and other soft foods but he has never bitten hard. Even as a new bird he never bit me hard, only soft bite with some pressure that hurt only if he got you at the wrong angle. So is it possible that my bird just doesn't like or know how to bite down hard?
