i have a hen that wont leave her nest box but to eat ........ the box is at ground level ....she stopped roosting with the other hens , and now spends all her time in the nest box !!! im guessing she is broody , however , is it normal for them to spend the night in the nest box ? she lets me take her out , but will run right back to the nestbox !!! i just wanna be sure she isnt sick or something .. oh yeah she didnt do it last spring ...
