1. Amish/Local Builders: Many build high-quality, large wooden coops, often available wholesale or customizable for bulk orders (e.g., Amish sheds and coops in PA and similar regional builders).
2. Large Online Retailers: Companies like OverEZ (known for easy-assembly) or Omlet (though often plastic) might offer bulk deals or have distributors.
3. Wholesale Suppliers: Search for "chicken coop manufacturers wholesale" or "farm supplies wholesale," as these companies sell directly to retailers or large-scale buyers.

• Wood Type : Cedar, Cypress, Redwood resist rot; avoid untreated pressure-treated wood.
• Waterproofing : Look for solid roofs, overhanging eaves, and sealed joints to keep bedding dry.
• Size : "Large" means ample space; consider coops designed for 10+ birds (e.g., 4x6 or larger).
• Design : Walk-in access, attached runs, and predator-proofing are key features in quality coops.

• Contact Manufacturers Directly: Ask about minimum order quantities (MOQs) for wholesale pricing.
• Consider RTA (Ready-to-Assemble): Flat-packed kits reduce shipping costs significantly.
• Check Reviews: Ensure the product quality holds up, especially for waterproofing and durability.
