ONCE A CHICKEN, ALWAYS A CHICKEN
Once upon a time, a hunter decided to rear chicken for the fun of having adequate supply of meat and money making. He decided to nurture his fowls with the best feed to made them grow with ease and stand out.
In the passage of time, his hens laid eggs and starting hatching them. He watched from a distance stupified by the quickness in their multiplication and labored relentlessly to rear them. One of the hens strayed into the bush carelessly with it's chicks and got back with a strange chick; the eagle. The hunter's friend warned him sternly about the strange chick but he flawed his advice hanging his hope on the tenet that once a chicken, always a chicken. Stuck to his guns, the hunter continued his routine paying deaf ears to warnings.
As time winds down, the chicks grew rapidly and the hunter wanting to prove his friend wrong will throw the strange chick in the bush and watch it return home to his friend's chagrin.
The bustle and hustle for food and feather ruffling exercises of chicken continued until the chicks grew up. A day came, the chicks strayed into the bush and the strange chick was gone with the wind. The hunter's fried laughed him to a scorn and comically mimicked his words 'once a chicken, always a chicken'.
So it was that the farmer knew that once an eagle always an eagle and once a chicken not always a chicken.
