i have a hen that will not leave her nest to eat or drink, shes been on the eggs almost a week, and i really dont think much, if any of the food i have in her cage has been touched, nor the water. her comb has gotten really pale and small, so i am starting to worry about her. i try to coax her out with a stick because she is quite vicious and strikes at me like crazy. should i just leave her be or get her out of there and not let her back in until i see her eat or drink? her food and water are close and within eye shot of her, and shes seperate from the others. any ideas?
