laying two eggs within a month?

[khutz]

hey all,

I have a beautiful 8 year old female cockatiel and recently she has laid not one, but two eggs in the same month. I'm not really sure how many they are supposed to lay or how often, so I was wondering if someone could enlighten me if they have any info!
thanks!

I have only had male cockatiels but I think they lay about three or four every clutch, I dont really know though
