4 yrs   + 3mos. The artist takes his 
Next step! ! He followed the directions from Jan Brett's online video "how to draw a chicken".  
I erased the line at the head and neck and explained to him to "make m's & w's" for the comb on the chicken's head and feathers on it's neck.  Also when he tried to draw one line for the chicken's leg I pointed out that "she (Brett) drew two lines on the leg".   I paused & started the video as he worked.
He's obviously not in preschool because when she said to draw a square for the beak he drew a perfect square.  :D  that boy sure can follow some directions though!  And he seems to have a gr8 sense of scale a lot of times!
