Sorry it is poorly lit in the barn and I only had my cell phone with me. These pictures are not the best.
There are at least 4 nests around the barn. You can't tell but this mama duck has about 6 more eggs tucked into her nest. We weren't sure if any of the eggs would hatch because they weren't very good about sitting on the nests during the first few weeks.
During the colder weather a month ago the nests were open for large periods of time. I guess that doesn't matter as much as we humans think it does.
