One of my Buuf Orps has been sitting in the nesting box all day. At first, I thought she was trying to lay an egg. Then I thought she was just sitting on eggs. However, I noticed she had shoved all the eggs out the back door & onto the ground (I have a raised coop). This evening, she was still there! I noticed her comb & everything that is normally a vibrant red are now a pale red, almost pink color. We forced her out of the coop, thinking she just needed food & water. She was able to run around, but she didn't eat or drink & when I turned my back, she returned to her box. I think she has been sleeping there at night too instead of roosting. Any advice?
