Cimuka 15-Inch Grow-Out Pen – Stackable Poultry Cage with Automatic Watering System

Raising young poultry takes careful attention to feeding, watering, and keeping their living space clean. The Cimuka 15-Inch Grow-Out Pen is a stackable poultry rearing cage designed for growing pullets, quail, pheasants, partridge, ducklings, goslings, young turkeys, and other game birds before they join the adult flock. Its rust-proof elliptical flooring, automatic nipple watering system, removable manure trays, and feed-saving grill covers help simplify daily care while keeping the growing area more manageable.

With lockable wheels, secure door latches, and a modular tier design, this grow-out cage suits backyard poultry keepers, breeders, hatcheries, and larger poultry operations. You can also add compatible layers as your rearing needs change, making it easier to expand your setup without starting over with an entirely different system.

Key Features

• Rust-Proof Elliptical Flooring: The flexible Comfortplast™ plastic flooring provides a more comfortable standing and walking surface than galvanized wire. Its design helps reduce foot-related concerns while providing a practical flooring option for growing poultry.
• Automatic Nipple Watering System: A refillable 5.2-gallon water tank supplies 12 steel nipple drinkers through an anti-algae silicone hose and antibacterial PVC pipe. Attached drinker cups help limit wetting around the birds and keep manure drier, reducing moisture in the rearing area.
• Removable Manure Trays: Deep trays slide out for convenient waste removal and cleaning. Regularly clearing accumulated droppings helps you maintain a cleaner environment for your growing birds.
• Feed-Saving Grill Covers: Red, shock-proof grill covers sit over the removable feeding troughs to help reduce feed flung inside and outside the cage. Each trough holds 6.5 pounds of feed, making it easier to keep feed contained and manage refills.
• Stackable, Expandable Design: Combine compatible grow-out pen layers with Cimuka brooding and breeding cages to build a tiered poultry rearing system. Optional layer additions let you expand your setup as your flock or production needs grow.
• Lockable Wheels and Improved Door Locks: Lockable wheels help keep the pen in position, while the upgraded door-locking system helps prevent birds from escaping during routine care.
• 15-Inch Internal Headspace: Each layer provides 15 inches of internal height for growing poultry. The flooring is sized to support birds during the grow-out stage, with weekly capacity depending on the breed and size of your birds.

Designed for Easier Poultry Rearing

Managing several groups of young birds can mean frequent feeding, watering, and cleanup. This Cimuka grow-out pen brings those tasks together in one organized system. The nipple drinkers provide a consistent watering setup, the covered feeders help reduce spilled feed, and the slide-out manure trays make waste removal more straightforward.

The stackable format is especially useful for breeders, hatcheries, and poultry keepers who need to organize multiple groups of growing birds. Before choosing a configuration, check the recommended weekly capacity for your species and breed to make sure the available space suits your birds as they grow.
