Im going to need them soon. Im looking for ones that are easy to put on and take off. Thoes big clunky alumnium/metal ones look like they would hurt my birds, that and it makes them look like prisoners! lol maybe i could get "the warden" in here to elaborate lol. There are a few on e-bay for like 7 bucks that are elastic/stretchy kind that look nice, but they will not fit adult birds..only up untill about 7 to 8 months old i was told. I thought about zip ties but i think they could rub/cut my birds as well. Maybe if i sanded the inside where their leg's touch and up on the edges of the zip tie then maybe it would work. I do like the colors they come in, that would make it easier to identifi my other bloodlines of my same breed. Thoughts?
