Grandpas Feeders Automatic Chicken Feeder Large Size - Zero Waste

Our review of the Grandpas Feeders Automatic Chicken Feeder finds it best suited for small backyard flocks that need a low-maintenance, durable feeding solution. Built from galvanized steel and using the original treadle design, this feeder shines for owners who want a pest-resistant unit that delivers feed on demand and reduces waste. The single biggest reason to buy is its combination of metal construction and anti-flick grill that keeps feed dry and in the trough while preventing chickens from tossing it out, which translates to lower feed costs and less coop cleanup.

Key Features

• Durable Galvanized Steel Construction: The heavy-duty metal body resists weather and wear so the feeder can last many seasons without cracking like plastic alternatives.
• Feeds 6 to 12 Chickens for 10 Days: With an 18 kg capacity the feeder supplies feed-on-demand for a small flock, cutting daily refills and hands-on maintenance.
• Zero-Waste Anti-Flick Design: The anti-flick grill and treadle mechanism stop birds from tossing or spilling feed, reducing waste and saving on feed expense.
• Pest-Proof, Weather-Proof Lids: The covered design keeps rain, snow, wild birds and rodents away from the feed so it stays dry and sanitary outdoors.
• Built-In Side Guards: Side guards encourage head-on feeding to lower pecking and injury risk and promote safer, calmer feeding behavior.
• Proven Original Treadle Design: A long track record provides confidence that the feeder will function as intended for many users.

Who It's For

This feeder is ideal for backyard chicken keepers with about 6 to 12 hens who want a tough, low-waste solution that can be left outside for up to 10 days between refills. It suits buyers who prefer metal over plastic and value pest protection and a tried-and-true treadle system that chickens learn quickly.

Those with very large flocks, commercial operations, or buyers who need a lightweight portable feeder should look elsewhere; the galvanized metal is durable but heavier and the capacity and design are optimized for small to medium backyard flocks rather than high-volume commercial use.

Pros & Cons

Pros

• Anti-flick grill and treadle design significantly reduce feed waste and messy coop floors.

Cons

• Metal construction makes the feeder heavier and less portable than plastic options for frequent relocation.
• Although many report long-term durability, a few users noted issues with breakage, so occasional checks are prudent.
