Thanks for the info. I can definitely separate the offenders from the flock once I find out who is causing the harm...but I dont have the stomach to use the specs, lol. From what i've read, you have to pin them through the nostrils. I cant help but think that it would hurt them?
They are called pinless peepers. They have them in plastic colors and basically they just hook on the nostrils. I used them once. You need to make them bendable by warming in hot water first, and then someone holding the bird and it's head still while you try to bend them into place helps.
