a grey with a bald spot?

[trail_rider]

I have a pair of tiels that I got from a breeder that was getting out of breeding. the female is a lutino, but i dont know if she is maybe a pearl lutino? she has some white and some yellow feathers all over her body. in sort of an alternating pattern. the male is a grey. he has a white spot on the back of his head about the size of a pencil eraser or a bit bigger. but what has me stumped is that he has a bald spot?? i thought that maybe she was plucking him, but when he molted there were no pin feathers there.......it was just bald. could he be split to lutino? can anyone tell me why these two might have been paired?

the white print is split to pied

he could of been plucked long ago and plucked so badly it ruined the feathers and they won't grow back

I have a few that are like that in the areas the damage was done the most the feathers will never grow back and it'll always be bald

Beleive it or not ANY mutation can have balding. Do you know the background of the grey? Most times breeding like to like...meaning same mutations together over several generations can result in balding. It is less common in normals, unless he had one parent (even non-lutino) that was bald.

To be on the safe side if he inherited the baldness from previous generations I would not pair him with the lutino. As to the previous breeder, she may have had him paired to the lutino if he was also split to lutino.
