Ok, my little girlies are 6 days old today. I went to the grocery store and brought them Stoneybrook Farms organic plain nonfat yogurt. Are they old enough to give it to them yet or do I wait another week? I remember reading that the live cultures are good for the little guys. Since they are on medicated feed I thought it would be a good idea. Also, if they are old enought to eat the yogurt do they need supplied with grit? If so I will wait and get parakeet grit from the pet store tomorrow night.
