Asymmetric eyes in albinism and fallow lovebirds- By the anatomy of African lovebirds, the eye must be perfectly round or at least proportional to the basic shape.
It is easy in the wild because mature and stagnant genetic conditions are the key to stable generations.
However, in the aviary, several mutations have affected the basic character of the eyes of African lovebirds, ranging from discoloration to cases with a too-small shape. And some are born with asymmetrical eyes.

What is an asymmetrical eye in albinism and fallow lovebirds mutation?
An asymmetrical eye is an unnatural shape in organisms specializing in African lovebirds. It is a birth defect, not a serious disease.
Asymmetrical eye usually occurs in the class of albinism mutations such as lutino, albino, and creamino. This albinism mutation affects the distribution of melanin in African lovebirds.
Asymmetrical eyes are also commonly found in the series; many African lovebirds, pale Fallow, bronze fallow, and dun fallow, have oddly shaped eyes.
Some forms of asymmetrical eye in albinism and fallow lovebirds mutation
Some cases of asymmetrical eyes have dilated eyes, and some form drooping eyelids.
I found the most extreme asymmetrical eye so far on pale Fallow; the shape of the eye looks as if it is torn and melted.
Causes of Asymmetrical Eye in albinism and fallow lovebirds mutation
The exact cause of asymmetrical eye is not yet known, but as far as my observation, this is caused by close breeding or crossing between close relatives.
Fallow series are still relatively rare and very expensive; breeders usually apply inbreeding to Fallow because they have limited funds to purchase different bloodline broods.
Because Fallow is a recessive gene, close breeding is used to abbreviate the acquisition of chicks with the fallow phenotype.
For example, crossing fathers with daughters, mothers with sons, and many other cross formulas still with close relatives.
The impact of repeated close breeding is that some individuals experience birth defects such as broken cartilage, lethal genes, and hair that is not as neat as it should be, and one of them is the asymmetrical eye.
Minimizes the occurrence of an asymmetrical eye on Fallow
Although the asymmetrical eye is not a serious disease and problem in African lovebirds, the acquisition of chicks with birth defects must be minimized to improve the next generation.
One way is to do cross-breeding; new bloodlines should always take precedence in fallow breeding.
Always start from a normal/fallow X normal/fallow cross for better results. Obviously, this couple has to be of different bloodlines, and you know the qualities of their parents.
Hope it is useful.
