It's been getting real cold, windy, and snowy here in Ohio recently and I have increased the amount of feed I am giving to my nine muscovies and one embden goose. The problem is...they have zero interest in eating. On the very cold rainy days they have no problem. I just call them and they leave the pond to come eat. They free-range my large property eating grass and whatever bugs they find this time of year. They are mostly self-sufficent and keep to themselves. They are not "people ducks". They will take note when I call them for food and mosey on up to eat, but they don't follow me around or have any kind of emotional attachment to me. They are on the wild side of how ducks can be. (I bought them as a young-adult flock and they were not handled by the previous owner.) I've been throwing food out for them twice per day since the weather has turned so cold. They have free access to several out buildings but they choose to stay in the water for most of the time. As soon as the snow starts and the temps dip to the 30's and below they show no interest in the food. They don't even want to leave their pond when I call them. Even when they are hanging out by the area where I feed them, they STILL don't show any interest. I had three females sitting 6" away from a pile of corn and showed no interest?!? Other than this they are all acting normal. No limping, no decrease in physical activity, no notable odd behavior. They just don't want to eat. What's up with this? I am new to duck keeping and have read that they need increased amounts of food during the winter, but I can't physically force them to eat. At first I was like...they must know what their doing, but now I am getting concerned.
