Lock Chickens in Coop at Night

Solution

Ensure all chickens are securely locked inside the sturdy coop every night from dusk until dawn.

Explanation

Most predators are active between dusk and dawn. The coop should be the most secure structure, and locking the birds inside provides the best protection during these high-risk hours.

Notes

Automated chicken coop doors can simplify this task but must be reliable and predator-resistant.
