I am using the spiral leg bands. The size recommended for Orpingtons is #12. They seem tight. How snug should they be? I am thinking about getting size 14 for these big girls. I put them on two young birds almost three months old. They are loose but do not seem too loose. They hang a bit like a bangle. Just do not want to cause injury my girls. They are still growing at only 6 months old.
