Provide as much room as possible, free of obstacles for both of these activities. Whether you choose a cage or aviary for your doves, there are a few basic rules to follow. Allow a minimum of 2 feet x 2 feet x 2 feet per pair of Diamond Doves. The more space that can be provided the healthier your doves will be. If space is in shortage, it is always better to give up on height than on length.
Enclosures can be from open wire all around to closed on all sides with a wire front.
Diamond Doves are a hardy bird, however, they must have escape from the elements. Drafts must be avoided, especially in colder weather and they do not do well in freezing temperatures. Determine what will work best for you and will fit best in the location you selected for the cage. If a heat source is needed, select one that is safe for you and your doves. Many fumes can be deadly to birds, and flying can stir up dust and feathers that are very flammable.
