Wow I posted then more showed up! Ok so you want to tell them apart. I keep a notebook write in it differences, I watched 24 cockatiels hatch and was able to distinguish each of them in a few days. Names well we get creative. One we named scoots cause he just scooted around, swiper stole things, then sometimes we get really odd and go countries on them choose names from different places. We had Belladonna, Hemlic, Venus and DeMilo, and a cat named Racoon! Wookie and chewbaca, jeckle... they all live up to their names. CHEWBACA we were told was a male sun conure. 10 yrs later we thought he was ill, writhing in the bottom of his cage. Later that day he laid a egg! Jeckle a cage mate cockatiel was the culprit. Only laid one egg. So now unless we are sure we use unisex names.
