A few years ago, a British geneticist, a philosopher and a chicken farmer pooled their resources and concluded that the egg came first. The first egg to have the DNA of a chicken would hatch into a chicken, said professor John Brookfield of the University of Nottingham in 2006. Brookfield and Papineau were speaking at the behest of Disney as a promotion for the film Chicken Little.
When a parakeet is about 3 or 4 months old, it molts for the first time. If your bird is younger than that, his head is adorned with stripes all the way from the forehead down the back of his neck.After his first molt, he loses the stripes from his forehead.hen a parakeet is about 3 or 4 months old, it molts for the first time.

At around one year of age, the cere, or pink fleshy nostril band above the beak, changes color in parakeets. This is normal and expected. In female parakeets, it changes to tan, pale blue, white or brown. In males, it changes to a bright, vivid blue, except for a few color varieties in which it changes to bright purple or remains pink. This color change helps to easily tell the difference between mature males and females.
