Stainless steel chain is a wonderful toy base for large parrots. You can string the chain through the toy parts and attach a link at either end. The 3.0mm chain (use the 3.5mm link) will fit any toy part with a 1/2" hole (or larger). The 3.5mm chain (use the 3.5 or 4.0mm link) will fit any toy part with a larger than 1/2" hole.
