Hello, I recently brought home a 4 month old cockatiel and was told that he was a dna tested male by the breeder and that he was a pearl. I joined a Facebook group and was posting pictures of him (I post tons of pictures of my pets lol I am a bit obsessive) and was told that he was definitely female. One because he has pearling and two because he has a yellow tail. Should I get another dna test or is he just too young and to tell since he hasn’t had his first molt yet? Either way female or male it’s my baby but it would be nice to know for sure because I thought I was sure before but now I’m not.
