I have taken in my sons bird. He is a green cheek conure and Im trying to learn how to take the best care of him that I can. So I have several questions. First what is birth rung mean? Is that something to do with the metal ring around his foot? What should I be feeding him? My son just had a bag of mixed seed. He also bites me a lot. How do I stop him from that. I want to hold him and stuff but he dooesnt always let me pet him. Please any info would be great.
