Can Ultra Flex-Pens be configured either individually or as a group — and how does that work?

Yes. The Ultra Flex-Pen uses removable center panels, allowing calves to be housed individually or combined into a group pen. This works by removing a side panel and replacing it with the available Group Housing Crossbar, giving you flexibility depending on your management strategy, barn space, and calf population.

Are the Ultra Flex-Pens easy to assemble, reconfigure, or move?

Yes. Because the pens are modular, light (injection-molded panels) and freestanding (no need to bolt to the floor), they are easy to set up, tear down, expand, or reconfigure as your herd or barn needs change. EZ-Glide connection tabs and hinges simplify assembly.

How does ventilation work with the Ultra Flex-Pen?

The pen includes rear rotary vents and sliding side panel vents to allow adjustable airflow. Proper ventilation is critical for calf health: fresh air circulation helps reduce moisture, odor, and airborne pathogens — decreasing the risk of respiratory illness and improving comfort.

What calf ages or sizes is the Ultra Flex-Pen suited for?

Ultra Flex-Pens are recommended for pre-weaned calves — typically up to about 12 weeks of age.

What materials and design features does Ultra Flex-Pen use — and why is that beneficial?

Pens are injection-molded using durable plastic/poly, making them lightweight for easy handling and cleaning, yet still strong and long-lasting. Panels interlock with EZ-Glide tabs and hinges for easy setup or tear-down. The pen also features “ultra” rear-rotary venting (no rusting metal parts), integrated sliding side vents, and a non-metal door frame — all contributing to biosecurity, ventilation control, and ease of maintenance.

How much space does each calf need when housed in a pen like this?

For calf pens, a commonly accepted guideline is at least ~28 ft² (≈ 2.6 m²) per calf. Additionally, pens should be large enough for calves to lie down, stretch fully, rise, and turn around — accommodating natural behaviors without restriction.

What feeding/water options come with Ultra Flex-Pen — and how is cross-contamination prevented?

The pen includes separate water and feed buckets, and molded calf dividers to prevent cross-contamination when housing calves individually. This helps maintain biosecurity and reduces risk of disease spread.
