ODD eye (heterochromia) Agapornis - Have you ever seen African lovebirds with different eye colors between left and right? This condition is rare and may not be planned in crosses to obtain chicks of the Odd eye phenotype.
Some call it flip flop, and some say birds with different eye colors are half-siders.
But you need to know that this condition has the name ODD Eye, just like in cats and other animals with different eye colors due to Heterochromia iridis.

What is Heterochromia Iridis
Heterochromia iridis is a condition characterized by differences in iris color in organisms. It can occur in animals, including cats, birds, primates, and humans. Heterochromia iridis is often called "heterochromia." or odd eye.
Each eye has a different color in the case of heterochromia iridis in cats. This can result in various combinations, such as one eye being blue and the other being green, yellow, yellow, or a different color altogether.
This condition can affect all types of cats and occurs in purebred and mixed-breed cats.
Odd eye on African Lovebirds
In the case of African lovebirds, odd eye generally occurs in albinism or NSLino mutations, such as lutino, albino, creamino, and NSL ino opaline.
For the Roseicollis species, I have never found lovebirds with odd eye abnormalities.
Although this phenotype is very rare, it really exists and is real. I have seen someone posting on social media pages several times.
But so far, I have only found the type of NSLino blue, commonly called albino.
Causes of Odd Eye in African Lovebirds
Heterochromia iridis, or odd eye in African lovebirds, is usually caused by variations in the distribution or concentration of melanin, the pigment responsible for eye color.
The genetic mechanism behind heterochromia, or odd eyes, in African lovebirds, has not yet been fully understood, but it is thought to be influenced by many genes.
As happened to the half-sider lovebirds obtained from a series of repeated crosses until the half-sider lovebirds appeared at one point.
