Verified step by step guidance

1. Step 1: Begin by identifying the key characteristics of the organism described in the problem: feathers, a beak, and the ability to lay hard-shelled eggs.
2. Step 2: Recall that feathers are a unique feature found exclusively in birds, making this a strong indicator of the organism's classification.
3. Step 3: Consider the presence of a beak, which is another distinctive trait of birds, used for feeding and other functions.
4. Step 4: Note that laying hard-shelled eggs is a reproductive trait shared by birds and some reptiles, but when combined with feathers and a beak, it points specifically to birds.
5. Step 5: Conclude that the organism belongs to the animal group 'Birds,' as these traits collectively align with the characteristics of this group.
