Steve,
Certainly, with a few caveats, you can give your b&g boiled eggs. First make certain that you wash them, & if you have nolvasan, make a solution of 2 TBS to 1 Gallon of water, & let them have a two minute soak in some of that. Second, always make certain that you keep your eggs refrigerated, *no exceptions*. 3 when you do offer the egg, make certain that it is well chopped up so that you can ascertain that the temperature is no higher than 106 degrees fahrenheit any where in the egg. Offer the shell as well, if your psittazen needs the calcium it will eat some of it, if not, well it should be a fun fling. Make certain that the egg is cooked all the way through, hard boiled, never soft. Remove any uneaten egg within 3 hours to prevent bacterial contamination. If your psittazen shows a taste for eggs, they are a good place to sprinkle live culture additives such as pro biotic or Ultra flora plus.
