Hi Tia, yes.. it can be normal for budgies to molt fairly often, depending on environmental and other factors. I also have only 2 budgies, but it seems like the amount of feathers lost (and how frequently) is way more than my 3 parrots combined!
Please read these links below. They contain some basic info and advice on budgie molts.
While I'm at it, here is the entire List of Stickies that can be found in the Site Information section and the General Budgie Talk info sections
Some good tips and info at your fngertips
. Best wishes for Ice. Soon he will emerge with beautiful new shiny feathers!
