I haven't a clue why but my female ducks ave really loose feathers compared to my drake. His feathers lay pretty tight together, when you pet him they are slick to the touch and water rolls off of them. My females however... not so much. Their feathers are loose to the touch and don't lay as tight as my drake's. Now my females are being weighed down in the pool and their feathers are wet. Do I need to go to the vet? Or is there something I can do??? Please help!
