I have a chocolate Muscovy hen missing. We think she is on a nest. Our other two hens and two drakes seem content. We have a 4her that said a Muscovy showed up at the Tillar town pond yesterday. He is not sure on the color or gender. You might check it out. If it is brown, let me know! Yours may just be under your house or something on a nest. If so, you will see her in about 35 days!
