I don't know what percentage of the mosquitoes they would eat, I suppose it would partly depend on what other interesting food was available to them. If you let them free range, they will go to wherever the food is. Muscovy ducks and Guinea hens are apparently particularly good bug-eaters. I know that some organic apple growers use chickens in their orchards to control the wide variety of flying things that attack apple (and other fruit) trees.
