🐾 Animal Overhaul

Animal Overhaul replaces the vanilla animal system with a fuller one. Animals are given advanced AI, dietary needs and biological cycles, so livestock no longer behave as mindless entities. The mod also adds a pregnancy check, and players can see how far along a mother is and roughly how close she is to giving birth. Breeding uses the standard vanilla items such as wheat and carrots.

Poultry and farm building are handled through the usual Minecraft controls. Sneaking with an empty hand and right-clicking a chicken coop or nest collects stored eggs, while a plain right-click shows how many eggs are inside, whether they are fertilized, and the minutes and seconds left until they hatch. Food troughs and water troughs placed next to each other connect visually and share their inventory and water levels when they form a 1x2 pair.

The mod runs on Forge only and is published for 1.16.5 and 1.21.1. Both the server and every player need it, and it is released under All rights reserved, so it is not open source. No required dependency is listed for Forge.
