I got my 4th egg in a row today but my duck isn't looking good. She looks like the egg laying is taking a huge toll on her..her feathers look all ruffled and darker each day, she was off white but now she's very beige!!! I'm waiting on an order of layer mash for her which arrives mid next week. Her current food is quite good- she gets scratch grain and duck grower.....so what's going on?.?? Anyone else had this happen?? Why is my duck wilting away??
