I've read some stuff on various containers and things and it seems to me like metal is best as rodents can chew through plastic? So then I wanted to go to Wal-Mart or like TSC or Home Depot, something like that, to get some of these metal trash cans or even order on Amazon but some of them are kind of expensive Well, turns out my mom found this one at our local dump/transfer station. Obviously free's good so if it's good I wanna use it? The only thing is it's kinda rusty on the inside bottom but I figure we could put a trash bag or something in and just our the feed in there or just put the feed bag directly in there and leave the feed in the bag. The other thing though is I have no idea how big it is as the sticker is worn off. What do you think? It looks bigger than a 10 gallon but obviously way smaller than full size 31 gallon trash can so I was thinking maybe 18 or 20? Which brings me to my next question: How much feed do you think it wi hold? I've heard a 10 gallon just fits 50 pounds?
