This is the first winter I have had with my pair of Ancona ducks. I'm just wondering how exactally do I keep them warm? It can get really COLD here in the winter. It's snowing where I am at right now. How do ducks keep their feet warm? Should I give them all they want in the winter? Also, wondering about getting a couple female chickens this spring. I saw somewhere on the internet that my drake could kill the chickens if he trys to mate with them! Is this true??? Thanks for all your help!
