I want to hatch some Muscovy ducks. How cold hardy they are? I am living in Connecticut and if I start hatching next week. When winter comes, they will be only 4 months old. Are they strong enough to survive in the winter? I have a 8 square fees coop for them, but I don't put the insulation and it is still very cold in the coop. I also quote some day old duckling. $121 with 14 female and one male. While the eggs from local breeder are only $10 for a dozen.
