Yolkbook - Production Dashboard

Know Your Flock. Know Your Numbers.

Yolkbook gives backyard chicken keepers a clean, purpose-built dashboard to track what matters — how many eggs you’re collecting, what your feed is costing, and whether your flock is pulling its weight. Log daily collections, monitor 7 and 30-day trends, and watch your cost-per-dozen calculate itself in real time.

Register for a free account on our hosted instance (donations appreciated), or self-host your own using the open source code.
