Thanks, Mike, great article. I suspect obesity might be part of the issue. Several years ago I had this horrible woman tell someone, right in front of me, that my birds were "skinny" because I "couldn't afford to feed them." I was too stunned to even respond, thought we were friends, I'd given her birds, and she was well aware I'd been battling coccidia, we'd been comparing stories for months. Needless to say, I was mortified and have never allowed a food dish to get empty since...
