My hens were looking a little shopworn on their backs from my rooster, Cyril's, amorous but inexperienced attentions. So I put aprons on them. How long can those aprons stay on? Should I take them off every once in a while? I'm just thinking that I know my bra straps itch and bind after just so long. I'd hate to think my poor chickaboos are having issues with apron straps. And a followup question - when will those feathers grow back in? Not til after moult?
