Zebra Finch wants spray millet, not a gabagool and vinegar peppers sangweech

Bread is just bird junk food, calorie-rich but nutrition-poor. And a poor diet of bread can even harm birds, causing a condition called "angel wing," where feathers develop faster than bones. Affected birds can't fly and the condition is incurable in adult birds.

So stick with seeds for the birds and save the bread for a nice sangweech.
