YANCHENG, Jiangsu, China — October 12, 2026 — As urban farming tightens and feed, land, and labor costs keep climbing, poultry producers worldwide are rethinking how every square meter of barn space is used. The answer increasingly lies not in building bigger, but in stacking smarter. Leading livestock equipment manufacturer Jiangsu Longlong Plastic Products Co., Ltd. — maker of the Jinlong brand breeding equipment — is highlighting how stackable egg trays, foldable egg crates, and space-saving transport cages are reshaping modern poultry farm design.
The Space Problem in Modern Poultry Operations
Whether you run a 500-bird layer farm, a commercial hatchery, or a broiler integration operation, the math is unforgiving. Each coop needs floor space for birds, aisle space for feeders and drinkers, storage for eggs, and buffer space for loading and transport. When land is expensive or zoning restricts expansion, squeezing more productivity out of the existing footprint becomes the single highest-return investment.
Space-saving poultry equipment solves this by doing more than one job per square meter:
- It stacks vertically during transport and storage instead of sitting idle on the floor.
- It collapses or folds flat when empty, cutting storage volume by up to 70–80%.
- It standardizes dimensions so egg trays, crates, and cages interoperate across the whole workflow.
Stackable Egg Trays: The Foundation of Efficient Egg Handling
The stackable egg tray is the most frequently handled piece of equipment on any layer farm. It moves from nest to collector, from candling station to packing table, and from truck back to the barn dozens of times per day.
A well-designed stackable egg tray delivers three measurable benefits:
- Stable vertical stacking. Integrated rim locking and anti-slip ribs keep a column of 10–15 trays from shifting during transport, reducing cracked-egg loss.
- Standardized footprint. Trays that fit the same crate and the same transport cage eliminate wasted air gaps and double handling.
- Nestable or stackable when empty. Trays that nest inside each other when not in use return valuable floor space to the flock.
Jinlong's 30-egg tray is built for exactly this workflow. Molded from high-impact polypropylene, it handles both table eggs and hatching eggs, stacks securely on standardized racking, and rinses clean between cycles. For larger hatcheries running multi-stage incubation, the AA-2 / AA-3 series trays extend the same stackable logic to setter and hatching operations, keeping egg orientation consistent from collection to chick pull.
Foldable Egg Crates: Collapsible Storage When Not in Use
Even the best stackable tray still takes up space once it is loaded into a crate — and when the crate is empty, that space is pure waste. That is where a foldable egg crate earns its keep.
Traditional solid plastic egg crates are durable, but they ship and store empty at full volume, meaning a truck coming back from market carries mostly air. A foldable crate hinges flat at the corners, collapsing to a fraction of its loaded height:
- Return transport costs drop dramatically. One truck can carry 4–5 times as many empty folded crates as rigid ones.
- Barn storage shrinks. Folded crates slide onto shelves or against walls instead of occupying whole aisles.
- Hygiene improves. Smooth, one-piece molded corners with accessible hinges wash down faster than riveted designs.
Jinlong's EC02 and EC03 foldable egg crates are engineered around this principle. Both are molded from food-grade polypropylene, accept standard 30-egg trays, and lock open firmly enough for forklift stacking but fold flat by hand in seconds. The EC02 targets mid-size layer farms and local distributors, while the EC03 adds reinforced edges for heavier hatchery-duty cycles and export shipping.
Space-Saving Transport Cages: Move More, Stack Higher
Beyond eggs, live-bird transport is where poor farm design costs the most per trip. Overloaded, poorly stacked bird cages mean higher mortality, stressed flocks, and failed veterinary inspections at the border.
Jinlong's SC07 space-saving transport cage is designed for multi-layer stacking on standard truck racks. Its key features:
- Uniform footprint that aligns with the EC02/EC03 crate family, so eggs and birds load on the same pallet pattern.
- Ventilated side walls that maintain airflow through a full stack, not just the top layer.
- Stacking lugs that lock cage to cage, preventing lateral slide on rough roads.
- Detachable doors for fast loading and washing.
For exporters shipping to Eastern Europe, the Middle East, and the Americas — markets Longlong already serves — standardized cage dimensions also mean containers are filled to the legal payload rather than to awkward cube limits.
Poultry Farm Design: Plan for Stackability from Day One
The biggest gains do not come from buying one clever crate; they come from designing the whole operation around stackability. When laying out a new barn or retrofitting an existing one, Jinlong recommends four principles:
- Standardize the footprint. Pick one tray size (e.g., the 30-egg tray) and build every crate, rack, trolley, and truck rack around it. Mixed dimensions kill stacking efficiency.
- Separate "loaded flow" from "empty flow." Loaded trays and crates move one way; empty, folded equipment returns on a different path. This prevents cross-traffic and cracked eggs.
- Use vertical racking in the egg room. If trays are stacked on shelves rather than pallets on the floor, the same room stores 3–4 times more.
- Size the loading bay for folded returns. The bay should handle the full stack of empty folded crates coming back, not just the loaded ones going out — this is the bottleneck most farms miss.
Founded on August 11, 2017 (formerly Yancheng Yongfeng Plastic Products Co., Ltd.), Jiangsu Longlong Plastic Products Co., Ltd. is located in the Yongxing Town Industrial Park in the Tinghu Lake Emerging New Energy Equipment Zone of Yancheng, Jiangsu Province — adjacent to the Ningjing and coastal highways for convenient logistics.
The company integrates the production of livestock and poultry plastic containers, plastic flower pots, and polypropylene engineering plastic modification. Under its "Jinlong" brand, Longlong supplies breeding equipment known for quality and practical, novel design. Products are sold across all 30+ provinces and cities in China and exported to Eastern Europe, the Middle East, the Americas, and other regions; its plastic flower pots reach North American and European markets. With in-house design, mature technology, leading production equipment, and rich manufacturing experience, the company holds a number of national patents.

Whether you are designing a new poultry farm from scratch or retrofitting an existing layer house, the quickest return on investment is usually vertical — stacking egg trays, folding crates flat when empty, and standardizing transport cages across the whole workflow.
