I used a small side cutters to remove bands like this and it worked very well and it’s easy to see to keep the birds leg safe. Have someone hold her still and/ or work at night. If she is a 4H bird and tame, any time should be okay. Good luck. Btw, love the name. That is my only child’s name. And she’s going on 23. So I loved the name Sophia before it came back around in popularity!
