I've been wanting some for the longest time. If you do have them, have you seen an effectiveness against mosquitos and other irritating insects since you've had them up? I guess another important question to ask: Is there any reason why I shouldn't put out bat houses if I am going to keep chickens? I don't think there would be a conflict seeing how bats are nocturnal and my chooks will be shut up in their coop at night; but it never hurts to ask. Also, I know all about bats and rabies. I have done my homework. According to the CDC, a bat with rabies is going to exhibit very non-bat behavior, such as being out during the daytime and being approachable, and common sense would tell me to steer clear of any bat that acted like that anyhow.
