Hi all. I'm new to ducks,and just got four ducklings in the spring. Lucked out and 1 drake and four females. They had no eating issues as they grew, and spent most of summer and fall living on our pond and free ranging. Now that winter is here, they are not eating their feed. Ive tried three different kinds and they pick at it , but Im really worried. they love their treats and I think that maybe I spoiled them? They won't eat scratch, oats,barley, crumble or pellets. Ive been feeding them, lettuce,kale,peas,corn,cucumber,watermelon. I know this isn't enough nutrition for them. Any ideas??
