Cimuka 15-Inch Grow-Out Pen for Poultry – Model GL40-03-1K

The Cimuka 15-Inch Grow-Out Pen (GL40-03-1K) provides a dedicated space for raising young poultry as they grow beyond the brooder stage. Designed for pullets, quail, pheasants, partridge, ducklings, goslings, young turkeys, and other game birds, this stackable grow-out cage combines easy-clean manure trays, controlled watering, and feed-saving grills to help simplify daily bird care. Its 15-inch interior height gives growing birds room before they transition to adult housing.

Made with rust-proof Comfortplast™ elliptical flooring, this poultry grow-out pen offers a different approach to wire flooring. The flexible surface is designed to provide more comfortable footing, while the enclosed nipple drinker system helps keep water cleaner and manure drier. Whether you're raising birds for a backyard flock, hatchery, breeding program, or agricultural operation, the modular design lets you expand your setup by adding compatible layers as your needs change.

Key Features

• 15-Inch Interior Height: Provides headspace for growing pullets, quail, ducklings, goslings, young turkeys, and other compatible game birds before they move into adult housing.
• Comfortplast™ Elliptical Flooring: Flexible, rust-proof plastic flooring is designed to provide more comfortable footing than galvanized wire, helping address concerns about foot comfort during the grow-out stage.
• Removable Deep Manure Tray: Collects droppings beneath the cage and slides out for easier cleaning. Regular waste removal helps keep the birds' living area cleaner and makes routine maintenance more manageable.
• Feed-Saving Grill Covers: The included red, shock-resistant grills sit over the removable feeding trough to reduce feed being scattered inside and outside the pen. The trough holds 6.5 pounds of feed, helping keep feeding areas more organized while reducing waste.
• Integrated Nipple Watering System: A refillable 2.1-gallon water tank supplies three steel nipple drinkers through a hose and PVC pipe system. Attached drinker cups help prevent birds from getting wet and reduce excess water around the manure tray.
• Stackable, Expandable Design: Compatible with Cimuka brooding and breeding cages, allowing you to combine different layers to create a tiered poultry housing setup. Additional layers can be added as your operation grows.
• Lockable Wheels and Improved Door Lock: Locking wheels help keep the pen in position, while the updated door-locking system helps reduce the chance of birds escaping during routine care.

Designed for Easier Poultry Care

Growing birds need regular feeding, fresh water, and a clean place to develop. The Cimuka grow-out pen brings several everyday tasks together in one unit. Its removable manure tray makes waste collection more straightforward, while the nipple drinkers and attached cups help limit wet areas inside the cage. The covered feeder helps keep feed from being flung out of the trough, so less feed is lost during daily use.

The stackable format is especially useful for hatcheries, breeders, poultry researchers, and keepers managing multiple groups of young birds. Instead of treating each growing group as a separate housing project, you can build a tiered arrangement using compatible Cimuka brooding, grow-out, and breeding layers.

Capacity and Model Selection

The number of birds this grow-out pen can accommodate depends on the species, breed, and age of your birds. Review the manufacturer's weekly grow-out capacity chart before choosing a setup.
