Read carefully and slowly - actually understand the words: it's a brain exercise I will delete your answer if you are right. If I had 4 eggs A thief gives me 3 My farm rooster lays 5 eggs How many eggs do I have? answer is

If you had four eggs, and a thief gives you three eggs, then your farm rooster lays 5 eggs, then you have THREE EGGS

Because you said that you had eggs and it is in past tense, then that means that you donot have them again.

A thief gives you three eggs, it is in the present continuous tense, which means you still have the eggs.

A rooster does not lay eggs.

As a result of this, you have THREE EGGS

Only 3 eggs I believe. "Had 4 eggs", is past tense, meaning that you no longer have them, and roosters can't lay eggs
