I bought a blue female with a white head (no idea about colors) She'd been mounted by 2 boys, but refused to be pregnant.

About a week ago her cere started crusting off. I wasn't worried, she'd just been treated for scaly beak. Now, it's light blue around the edges, but the dark brown bit is still there, between her nostrils.

 

Does this mean she's always been a boy and her previous owner was desperate, or do I have another Peanut (She was an albino who's cere never colored, so she was kept as my pet.)

Skye is a female who's gone out of breeding condition. The dark brown bit will flake off and her cere will go a whitish blue. Then when she comes back into breeding condition here cere will go brown again.

Here is what you are seeing... a brown cere flaking off and becoming blue/white.... I bought Sophia and her entire cere was crusty brown... This is a picture between the time that it was fully crusty, to blue with white above the nostrils...

 

 

 

Here she is now (on the left) without the crusty brown cere...

 

 

 

Don't be worried about it!

Thanks for informing me. Why/how can a girl's cere go blue?

Caren, it's hormonal. The cere turns a dark crusty brown when she is in breeding condition, the rest of the time it is pale, and sometimes tinged with blue. It's perfectly normal

My Pattys cere is constantly brown never goes pale again!

It's quite normal, though Sophia is the first of my budgies to actually loose the crusty brown cere! All the others haven't lost theirs, and currently my other female, Georgia, still has hers. Can't say for sure if she is going to loose hers or not...
