First I'll say I know almost nothing about ducks. I'm not even sure I have mallards. The father of my ducks is a green head, and the mother is a beautiful mocha color. I have 2 male ducks that look similar to their green head father, but their heads are jet black, and their bodies are bigger. Anyway, I am not an animal lover, but I gave in to my kids and husband and allowed ducks thinking, and hoping they wouldn't last long. Jokes on me because I LOVE them so much more than any other animal we have ever had. I am the primary caregiver, and I enjoy every minute of it. It is now November and getting pretty chilly, it's actually lightly snowing right now. I have penned them for the last 2 nights to keep them from quacking and bothering the neighbors, but other than that they have free range in the 1/3 acre yard. They have a swimming pool, and a large pet porter (big enough for 2 full grown German Shorthairs with room to spare) with straw and food and water in the pet porter. The pet porter is positioned between a tool shed, and wood fence to help block the wind, and also wrapped in insulation. Even in harsh weather they don't go in their shelter. I don't know if I should force them in, or if they will just go in on their own when they need. Right now as it's snowing they are in their pool so I feel like I am worrying for nothing. Any advice would be much appreciated.
