Use 1/2-inch hardware cloth on all openings

Cover windows, vents, and any gaps in coops or hutches with 1/2-inch or 1/4-inch hardware cloth (heavy gauge welded wire mesh), fastened with screws and washers or heavy-duty staples. Chicken wire is not predator-proof — raccoons can tear through it or reach through the 2-inch hexagonal holes.

Why It Works

Hardware cloth has small, welded openings that prevent predators from reaching through or tearing the mesh. Raccoons, weasels, and snakes are the main threats that exploit gaps. A 1/2-inch mesh stops raccoon paws; 1/4-inch mesh also blocks snakes and weasels.

Tips

• Fasten with screws and fender washers rather than staples for maximum security
• Check for gaps at corners and door frames — weasels can fit through openings as small as 1 inch
• Wear heavy gloves when cutting hardware cloth; the edges are razor-sharp
