It is tricky because humans are biased for intuitive understanding rather than logical understanding. Intuitions are shortcuts that are very valuable, but sometimes they are just plainly wrong. Many people will try to apply intuition rather than logic because that works with many other similarly worded questions.

Still don't get it.

The imho intuitive answer is the right one.

I really tried to get what could be tricky about this question. But there is just nothing.

I have no clue how anybody could arrive at anything else[†] than 48. It's trivial. There is no "puzzle" at all.

† (As long as you don't consider RL biology, as than then there is no definite answer, only some probability.)

I think it is an issue of language "3 hens lay 3 eggs in 3 days" can be interpreted (as intended that each hen lays an egg only once every three days) or as implying that it is implied that they mean 3 eggs for each hen over the three days, meaning 1 egg per hen per day (incidentally closer to what actual commercial hens lay, not that this matters).
