Zebra mutations how have I produced this !!!

[Fraza]

So out of all my zebbies I have produced a pure white and then a what it looks like black face normal with a funny tail I’m really confused how I have got a white zebra chick when not one of my zebras is white and I only have one pied ????? Also it has no tear marks, pic below

The Java’s have done that to its head let’s just say one of the java fledglings is abit nasty

The white one is a pure white cuze its beak is not fully pink, i think it's a solid pied, its head is abnormal, was it well fed, it has some growing retard, sometimes i think it's a hybrid lol
for that grey to have bf u should at least one of bith should be BF as it's dominante, if it's not tje case, it's only a fault due to tha lack of light in the nest

haroun well they got fed okay but I have noticed that they feed the grey one about 70% then they only feed the white one like 30% also it has no tail bars ??

I’m so confused have u ever had this
