I actually use a pocket sized digital gram scale, and it works perfectly. I used to have one of those perfect polly toys, and, well, the birds hated that thing. So I got rid of the toy, but kept the perch from it and I now use that on the gram scale to weigh my flock in the morning.
Thank you for my wonderful signature Deb!!!
