It seems to be a simple solution: in SC at least, a 6' high 10'x10' dog run is $100-200. Maybe the stepson should buy it since it seems to have been his actions (and his dog?) that caused the loss.
Contain the dog, contain the chickens, teach the kid a lesson the only way kids learn - saving your allowance to buy new chickens and a dog run when you would rather go to the movies is pretty steep motivation to double check the next time.
