Breeding Zebra Finches is fun and easy. These little birds are breeding machines, requiring amazingly little the aid of their human companions. They will produce young birds with an impressive rate and so they aren't particularly picky about where they are doing it. Almost any enclosure will perform if you produce an appropriate nesting site to allow them to lay eggs, incubate them and nurture them until they become independent. Also try and get some moderate exercise - lifting your heart rate is enough 3 times a week.
