Well that stired up some imagination. But I want to stay away from the saucers. I like john in wa idea of just big holes they can reach into. Want to try that.
I like your ice cream bucket idea Valley quail breeder. I think the oval ones will work for the breeder cages. I am sure DH will not object to me stocking up on ice cream. If I cut the holes to high I 'll just get more ice cream and try again.
I just emptied a 2# peanut butter jar - should stand in the corner and not take up to much room. I sure use a lot of peanut butter because of my quail, (Lids for feeders for chicks). Jar might not be big enough though. Needs to hold 2 cups and not be more than 3 inches deep to have holes in it and no saucer. Might Work better than those Quail Feeders I bought though.
I Can us a spring to latch either in place too. Cool, I am going to try these.
