* Chicken wire. Chicken wire is similar to mesh wire, but it is made of thinner wire and has larger holes. Chicken wire is not as strong as mesh wire, but it is less expensive and easier to work with.
* Hardware cloth. Hardware cloth is a type of wire mesh that is made of heavy-duty galvanized steel. Hardware cloth is very strong and durable, and it is often used to cover bird cages that house large or aggressive birds.
* Plastic mesh. Plastic mesh is a good option for covering bird cages that are located in humid or damp environments. Plastic mesh does not rust or corrode, and it is easy to clean.
* Fabric. Fabric can be used to cover bird cages, but it is not as durable as mesh wire or plastic mesh. Fabric can also be more difficult to clean, and it may not allow air to circulate as well.
