My young gold laced Wyandotte has been acting broody to me for the last month. She has been staying in the nest box all day and night, and only eats and drinks when I lock her out of the coop in the later afternoon after the other ladies are done laying. She sits on the others eggs all day, and doesn't seem to be laying herself anymore. The moment I open the door to the coop back up at dusk she books it right back in to the nest box. Is this broody behavior? If so, and I do manage to find some hatching eggs, will she remain broody to hatch them out, and will they all be ok being born in the middle of the winter? The coop is lighted, but not heated at all. She was a mid april chick, so in her first year of life right now. We have had an unseasonable warm winter so far, but now its frigid out.
