I haven't dealt with chickens since I was a child. Many years ago. So, I have a 15 week old black sex-link. Last night she was laying on the floor of the coop in a corner. Concerned, I set her in a box of pine shavings for comfort.this morning she was still there. She didn't perk up at all when I lifted her and saw that the shavings were wet and a white pastie stuff was under her. I changed the bedding and noticed the same thing on the floor. I cleaned her up and stood her on the floor but she was very unsteady. I offered her some corn and she would not eat or drink. I am very worried. Anyone have an idea what is wrong or what I can do?
