Can you give a rat a plain, ordinary egg that hasn't been cooked? What ways to cook an egg are healthiest or safe (hardboiled, scrambled, etc.) ?
I saw a YouTube video where the owner just put a hard boiled egg into the cage with the shell and all. they didn't bother cutting it up into non-chokable pieces. is the shell safe? and is a full egg too much protein in one sitting? I'm not sure how eggs can be preserved to be eaten later.
