I believe that any birds that are kept in a stock loft definately benefit from the access to an aviary Steve, so that would be a must for me. My aviary is 6x3 and 7ft from top to bottom and the stock birds have access 24/7. Steve Burton uses and manufactures automated water supplies for lofts but not sure if he is on here but he's definately on one of the other sites if you want to contact him.
