When a friend changes his appearance we hardly get to recognize him but that doesn’t change what we feel for him. we accept him no matter what like this chicken does with his human friend, a boy who came after a while with something different in him.
The boy had a haircut and the chicken is cautious analyzing the situation because the bird knows that is something familiar with that little boy who arrived. When the chicken recognizes the boy hugs him like an old friend who is happy to see you.
Chickens also have an intelligence that not a lot of people know about, they are friendly with the ones they love.
