During our last molt -- yes, "our"

, I felt like I was involved, too -- ALL FOUR birds molted at once. Two grumpy budgies and one grumpy parrot (Jade wasn't grumpy but Clyde was). I got nothing else done but picking up feathers, and started saving them in a jar so I could make feather art. Seems like every day I found a couple of tail feathers, a few wing feathers and a few I couldn't identify. And budgies shed little fuzzy feathers constantly, but they were losing tail and wing feathers, too. I thought they never WOULD stop molting, but they finally did. This was the third molt we've been through with Clyde, and his take about a month, all told. Jade was faster, maybe a couple of weeks. The budgies started and stopped and started and stopped and it was probably about a month before they were completely done, too.
The good news is, new feathers are coming in as old ones are falling out, so even though it looks like they're going to lose them all and be naked, they're not!

It's like dogs shedding, if they did it all at once. I know I sweep up enough dog hair in any given week to make a whole new dog and I always wonder how they can lose all that hair and not have bald spots. The birds are the same way.
