I'm an extreme chicken newbie, 3 days to be exact. I'm using a mason jar chicken feeder and haven't had to refill it yet. I don't know how to open it up without the feed getting everywhere. I don't want to wait until the level is below the glass before I fill it and risk having them run out of food while i'm at work. I'm sure you veterans are getting a chuckle out of my silly question. Hopefully i'm not the first one who couldn't figure this out.
