stress bars

I have just learned that the bars on the feathers of my baby yellow gouldian mentioned in yesterday's posting are most likely stress bars, which are usually due to nutritional deficiencies, getting cold, or other health problems.  Since this baby was neglected then abandoned by it's parents before I started to hand feed it, it makes a lot of sense.  It is doing well on on hand feeding and will hopefully molt out to be a beautiful bird.
