I have right now 8 budgies which I adopted from my local animal shelter. Need some clarification on a topic I usually clean the inside of their cages with a small vacuum never had a problem before they have never been frightened by this before, had an incident recently where one of my birds got scared for some unknown reason and flew in front of the nozzle an got caught no damage done but people are belittling me for this and like I said been doing this for years and this is the first time this has happened. I need some input on this.
