Explanation:

To form a compound sentence, we combine the two related ideas. The first part is "Baby geese, unlike most other young birds, are covered with soft feathers" and the second is "they hatch with their eyes open". We use a conjunction (like "and") to connect them properly. So we structure it as: Baby geese, unlike most other young birds, are covered with soft feathers, and they hatch with their eyes open.

Answer:

Baby geese, unlike most other young birds, are covered with soft feathers, and they hatch with their eyes open.
