I can't be the only old fashioned mind here. Does anyone still use make-'em-yourself homemade wooden feeders? How do you sanitize such a thing? Maybe you don't cuz wood too porous to be doused with liquid. Maybe just dry brush 'em out and scrape off poop. Plastic cracks, metal rusts out, I really don't think wood is any worse, in fact, it might just last longer. And you can just make another! Anyway, I have a nice upright, wooden trough that works real well, and after my current flock is 'gone' I don't wanna just toss it due to poss. 'contamination' of a new flock. I wanna keep using it!!! Any thoughts to offer???
