What is the recommended bar spacing for a bird cage for doves?

I suggest you to have a look at http://www.birdcages.com/helpfulinfo.cfm. I personally purchased a parrot perches from their site and I was very pleased with their customer service and their products. If you're looking for a bird cage you'll find it there.

In general, the larger and the more active the bird, the larger the cage one should use. The amount of time the bird will spend in the cage each day is also a factor. A bird that is caged most of the time requires far more space than a bird caged only at night.

My recommendation is to call the manufacturer for paint recommendations and, believe it or not, some cage manufacturers will do that for you. In any event, you must make sure the paint is nontoxic since most birds do scratch it with their beak. After painting Make sure you let it dry completely: Permit the paint to dry for at least 48 hours before moving your bird into the cage, so be prepared to have a secondary cage on hand. Also you should know that although paint may be nontoxic when dry, there are paints may be harmful to your bird if inhaled, so paint it as far as you can from your birds, outdoor area preferred.
