we got ours from the feed shop, northener, like an upside down plastic bucket on a big saucer with a gap in it, holds 3 days worth for our 13, got another, smaller one they have to peck to get corn out but that was way expensive..they're both hung up from the bars under cover so, nothing can eat it but the chickens unless they throw any on the floor and leave it, hope you can get sorted :)
