My ~20 week old BLR Wyandotte hen seems to be sick. She hasn't started laying yet. We are new to this chicken-keeping. This started four-five days ago when she started hanging in the coop all day nestled into the bedding. It seems very difficult for her to put weight on her legs. I need to go down and get ahold of her for a better inspection. I was just observing her and gave her some black-oiled sunflower seeds, which she gobbled up. Now I want to go try to get her to drink some water. Any thoughts?
