Okay originally I had milk crates, they looked nice but didn't seem to fit the bigger hens. So I redesigned them using stackable type storage bins (not stacked, but side by side instead). I put the chickens in there from time to time and say "Egg" Do you honestly think they'll know where to lay their eggs? All my chickens are older (4+ months) when I get them and their previous homes had traditional nesting boxes. Think they'll catch on?
