Mississippi John Hurt's song "Chicken".
It is also on "Avalon Blues" the tribute to Mississippi John Hurt, where children are contributing to the singing.

CHICKEN

Chicken, chicken
You can't roost too high for me
Chicken, chicken
Come on out of that tree
Chicken, chicken, chicken
You can't roost too high for me

C        is the way to begin
H        the next letter in
I        am the third
C        For two C's in the bird
K        is to fill him in
E        I'm near the end                        
C-H-I-C-K-E-N
That's the way to spell chicken
