Are 2 year old laying hens good to eat?

I'm curious, are 2 year old laying hens still considered suitable for consumption? I've heard that their egg production declines with age, but does that affect their taste or nutritional value? Is there any risk associated with eating older hens compared to younger ones? Additionally, are there any specific preparation techniques or recipes that are recommended for 2 year old laying hens to ensure optimal flavor and texture?
