According to general captive feeding standards, how should grass hay provision be managed for wallabies?

Answer

It should be available ad libitum (freely)

Grass hay serves as the absolute foundation of the captive wallaby diet, supplying essential fiber, bulk, and promoting gut motility. Because the wallaby is designed to spend a considerable amount of time foraging and consuming roughage, the management standard for providing high-quality grass hay, like Timothy or Orchard grass, is to make it available ad libitum. This means the animal has unrestricted access to consume hay whenever it desires. This contrasts with commercial pellets, which are provided in measured portions to control protein and energy intake, reinforcing the primary role of hay as the constant roughage source.
