If the 38 ft cow were real then the chicken height will be 9.3 ft.
Explanation:
Height of the cow statue = 38 ft.
Actual height of the cow = 4ft 5 inch
= 4.41 ft.
Scale factor = 38/4.41

height of the chicken = 13 inches
= 1.08 ft.
Height of the chicken = 8.6 x 1.08
= 9.3 ft.
If the 38 ft cow were real then the chicken height will be 9.3 ft.
