Thanks for the advice! The ducks has a house that they go into to lay the eggs with hay....Their feathers looks like they just got out of the pond and the feathers froze wet. They are still laying everyday as well as the chickens..I guess they are happy! By the late afternoon, they are thawed out but it still worries me. I had to put a tarp around the outside yard to prevent wind because it did get pretty gusty the other day. No signs of sickness....but as I said earlier, this is my first year with poultry and ducks and I don't want to do something that will cause them to be miserable!
