Found this on one of the websites, and thought I'd pass the information on.
Please note: Galvanized metals contain zinc and are considered toxic. Galvanizing is a process to coat wire or metal to prevent it from rusting. The ingestion of small amounts of zinc by certain birds (psittacines) and small animals (carnivorous mammals) may, under certain circumstances, lead to a condition known as zinc toxicosis. When building aviaries or cages, thoroughly wash them with vinegar or a mild acidic solution and brush mesh to remove all loose zinc particles. Ensure that no particles are left on the floor of the completed installation. If you have birds in a large aviary with lots of branches or items to occupy them, they are much less likely to chew on the cage wire. Galvanized after welded wire has less pooling and flakes less. Many thousands of tons of zinc coated wire mesh have been used for over three decades without significant problems but users can minimize any risks involved by following the above precautions. |
