Lovebirds exercise by flying and playing. They should have as large a cage as possible, they are very active birds. Be careful what you buy for bird toys as we have had birds hang them self in the rope from the toys. We have switched to only buy toys from Chew Too Toys, they use a special rope that will break and not hang your bird, find them at http://www.chewtootoys.com.
