The Purple Ones Tastest the Bestest
Sticking to the theme of what chickens like to eat,  I bought them cracked corn which includes both yellow and purple corn.   I first noticed with Hattie that she would eat the purple ones and throw the yellow ones to the ground to find more people ones.   When all the people corn was gone, she would stop eating and expect me to get more from the bag.   She would flick the yellow corn off my hand with her beak until it was empty so I would get her more purple.  I got video of Maleficent doing the same thing,  picking the people ones out.  Can they really taste that different?
