You sure can breed them! Infact, I'm going thru the exact process right now. Buzz is our male whiteface. Auzzie is the female cinnamon pearl whiteface that should be laying her third egg tomorrow! I am a BIG fan of any whiteface mutation and have been waiting on these two ever since they reached breeding age. There is a good chance the female chicks will look like the mother and the males will look more like the dad. At least that's what we're hoping for. This will be our fourth clutch but the FIRST whiteface babies!

 

Unless your white faced male is split for cinnamon and pearl, the babies won’t look like their mum.
Cinnamon and pearl are a sex linked gene like ino, which is passed from father to daughter not mother to daughter. As examples: pair a normal white faced male (not split for anything) to a white faced cinnamon pearl female, all the chick will be white faced normals but the males in the clutch will be non visual/split for cinnamon and pearl. Females can not be split for a sex linked gene, they either are or they are not.
Pair a white faced cinnamon pearl male to a white faced cinnamon pearl female and all the babies in the clutch both males and females will be white faced cinnamon pearls.
Pair a white faced cinnamon pearl male to a normal white faced female and all the cinnamon pearls in the clutch will be females and all males will be normal white faced/ split for cinnamon pearl. Hope that helps.

 

you will have WF(white face) chicks and WF pearls. now lets say the female got her pearl gene from her mother, the visual(able to identify from just looking at them) WF pearls will all be females and visual WF will be males. if the mother got her pearl gene from her father then all visual WF pearls will be males and all visual WF will be females

 

Hi my name is Kala.
I’ve owned and loved cockatiels since I was 14 about bought my first baby for 50 dollars and bought him everything he needed and from that point on I did with my own money. I’m 30 now and many cockatiels later.
I currently have a white faced pearl female cockatiel. I am acquiring another, very possible it’s male. He’s a white face. Can I breed them? If so, what could the babies look like??

Thanks,

Kala

If the other bird is male and just a normal white faced and not split for either pearl or cinnamon then all the babies will be normal white faced but the male babies will be non visual/split for cinnamon and pearl. Females can not be split for a sex linked gene. Both cinnamon and pearl along with the ino gene is sexed linked and is passed from father to daughter.
