Genny, you may want to get some false eggs for her. Not everyone will agree but I feel it encourages birds to stop laying and go broody when there is something left in their nests. You can likely find some plastic Easter eggs this time of year in a dollar store. Weight them with sand so they are about as heavy as a duck egg and glue or tape the halves together. When she goes broody, you take back the plastic eggs and give her the real ones. Don't worry about keeping the numbers the same... birds can't count. My American Buff goose went broody just a couple of days after my sister put one marble goose-sized egg in the nest. It was a bit of a joke, because when I picked it up it was much heavier than a real goose egg and very smooth. I couldn't figure it out until I saw her laughing. LOL. Sisters! But it did the trick.

Since she's a wild duck she's a seasonal layer and not really designed to keep laying one clutch after another. Ensure that she's eating a well balanced diet with sufficient protein and calcium. A layer feed and lots of greens should be sufficient. Wild ducks are excellent mothers and nesting/brooding instincts are very strong. Maybe someone else in your area raises ducks and has some fertile eggs your duck could raise. You could sell or keep the ducklings when they're grown.

GoldenPond, Yep, your on the right tract. I don't let my ducks out untill 8:30-9:00am, and their eggs are layed. Sounds like we have the same set-up. Sometimes they decide to stay out all night(naughty little kids) and I hear the girls 1/2 to an hour after sunrise laying their eggs under my bedroom window. That makes up for staying out all night because......We LOVE Those Eggs!!!!!!!

This is my first winter with chickens. My coop is a renovated 14'x14'x10' mini-barn. I re-shingled and cleaned it all up but I didn't insulate it. (I have mixed feelings still on whether to do that or not because of moisture issues). Our temperatures here went down to 15-20 degrees so I started to track the temp in the coop. It's been reading the same inside as the outside. I bought a heat lamp and started using it just during the daytime when it went below 35 degrees and I'd shut it off an hour or so before dusk - hoping that the warmth might last through the night. It didn't. [And Roberta, I did turn it off too late one night and the girls were so confused. They didn't find their roosts and just stayed where they were when the light went off - especially since 2 of them sleep up in the rafters]. So I bought a red light and decided to try and leave it on all night (using the thermostat) over the water & food area since it's not as bright as the clear light. Big mistake. I don't think they slept at all. They were bickering and picking on each other the whole next day. When it was time to bring them in at the end of that day, I gave them some treats and sat down to watch them for a while. When they plopped down in the bedding I thought they were going to start their dust bathing. But within 5 minutes each one tucked in their head and went to sleep. They were so exhausted and I expected to hear them start snoring. After this experience I decided to go back to my original routine of just using the light during normal daylight hours for a little extra warmth and no light at night. My only concern (with the cold nights) is for their comfort and combs. I'm not concerned with egg production since these girls are pets for me. Sorry this got so long. Stay toasty all and Happy Holidays!
