Hi, there are very experienced members in this group can tell the approximate age for budgies that are completely white with red eyes or completely yellow? I wonder how can you tell the age if budgie is young or not, since their cere don't change color as they pass the baby stage, they don't have any head barring or they never form iris rings their entire life. So I am very curious what is the magic trick to tell the age if these guys are babies or adults? Thank you
I will proceed to copy/paste the reply: Albinos will generally develop irises and only the males will keep the immature colour on their cere. Females of all colour mutations will go through the normal changes when maturing and going in or out of breeding condition.
Still, it surely is trickier to age albinos and lutinos, dark eyed clears are even trickier to give an accurate age estimate as these don't develop irises.
To look for clues (besides iris development), I mostly look at the size of the cheek patches (even in albinos these can be visible as they are a brighter white).
Most young budgies will have smaller cheek patches that after the first moult is completed will be a bit larger and fuller.
I also look at the toenail length and the overall body size of the budgie.

You are missed and never will be forgotten.
