I tried the Lixit bottle for almost a week, because I was hoping the water would stay cleaner and I wouldn't have to change it everyday and waste all the bottled water. But, after the first day I decided to open the bottle and smell the water which appeared to be clean, and it stunk! So I cleaned it out and tried it again, and the same thing. I think what was happening was Babalu would carry his food over to the bottle, eat, then drink. I think there must have been some backwash or something. So since I had to empty the bottle anyway everyday, I switched back to the crock. I have seen many bird stores using bottles though. That was my experience though.
