conure weights

So I bought this scale: https://www.amazon.com/gp/product/B07D3PWMSY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 (on amazon it's only 9.99 now or 2/3rds off it regular price,) so I could keep track of my new conure's weight. Now this scale is not calibrated. but it's enough to track weight...
