Final answer:
Each hen can lay one egg per day. Therefore, two hens are capable of laying a total of four eggs over the course of two days.
Step-by-step explanation:
The question essentially states that each hen can lay one egg per day (four hens lay four eggs in four days). Therefore, if we have two hens instead of four, the number of eggs laid would remain the same (one egg per hen per day) over two days. Thus, two hens would lay a total of two eggs per day and four eggs in two days.
