how long do chicken eggs stay fertile
most people say that you can hatch fertile eggs that are up to about 10 days old, perhaps even longer. After about 10 days your hatch rate goes way down. A hen can store live sperm in her system for up to about 3 weeks, so even if a rooster goes away, the hen he was with can lay fertilized eggs for up to three weeks.
