Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to keep multiple button quail [title] Provide a spacious habitat. [step] Button quails need room to move around. Ideally, they would be kept in an aviary where they would have room to run around the ground.

Ending1: You can also place them in a single area in the vet's office where they will receive air and exercise. [substeps] You might also consider creating a well-lit area where you can train one or two more button quails. Ending2: However, as long as each bird has about eight cubic feet of space to run around in, that should be sufficient. [substeps] The bird's cage does not need to be very tall because they stay on the ground. Ending3: If you have a large fenced in backyard, consider keeping multiple button quails with a large tank. They may become aggressive before catching a predator, so make sure the cage they choose has solid walls and lots of room for them to move around. Ending4: Create a small aviary for your button quail and space it inside three small cages. [substeps] Find a good dark spot where the quail cannot easily get out.
