Jack Pro Series Heavy Duty Chicken Netting is made from a 1.4mm galvanised steel wire, offering a robust combination of strength and reliability. As a heavy duty all-purpose woven steel netting with an aperture of 5cm, it is ideal for poultry yards, chicken coops and other animal enclosures, plant protection and garden trellising. Note: It is recommended that new galvanised wire mesh used in aviaries and pet cages be treated to remove excess zinc that could possibly harm pets. Shave off any zinc spikes with a utility knife. The mesh should then be scrubbed with a mild solution of vinegar (2 cups in a bucket of water) and rinsed with clean water.
