To figure out if its a male, you will notice bright yellow cheeks.. obviously bright orange/red cheek circles on yellow. Males also sing very loud and they move around a lot. Females are quiet and not as colorful. I can't say its a boy or not but if its under 1yr the eggs are probably infertile. You could wait 21-28 days and if nothing is hatching then throw them out (or bury them with a RIP rock like I do!) and get a cuttlebone and they will lay eggs again when nest is clean and empty. No more clutches than 2 per year.

I think I have provided all the info.

If anything is missing Please ask me, I will provide more info.

I brought a pair of cockatiels last feb 16. They said grey is female and lutino is male.

But in july, lutino has laid 5 eggs. It laid 1 egg for the first time. It laid 1 more the next day. It laid 3 more after 15 to 20 days. I have a doubt whether the eggs are fertile or infertile because i do not know the exact gender of the other. When i broght the grey cockatiel , it had dull yellowish grey face and dull orange spot on cheek, many bars and spots inside its wings and tails. It has yellow spots on its neck(back). In may to june, its face colour changed to bright yellow, and it has a bright orange cheek patch. there is only 1 spot in its wings(both left and right). Its tail has bars and spots but some tail feathers are purely dark grey. I WANT KNOW WHETHER THE GREY IS A MALE OR FEMALE AND WHETHER THE LUTINO'S EGGS ARE FERTILE.
