Many poultry nutrition experts now report that feeding excessive amounts of calcium can lead to basically, “loving your birds to death,” giving them too much of a good thing. Excessive calcium can lead to their premature death from kidney failure. If a necropsy was performed, it would indicate that the bird perished from gout, which is an excessive build up in the kidneys, indicating either too much protein or calcium in their diet.
I was truly shocked to read that the majority of the domestic ducks and geese that I was familiar with have severe population problems! There are six breeds of ducks and four breeds of geese that have numbers so low that they have been designated to be critically endangered. In addition to this disgusting revolution, there are ten more breeds that fall into the Rare and Watch categories.
