So my good laced Wyandotte is about a month younger than my big girls, but she's recently seemed to pull her neck to her chest and doesn't walk around with her head up of that makes any sense. The few days she's seeming to separate herself from the group of hens. Any ideas? She also is smaller (but significantly so )than everyone else and doesn't seem to eat as much, but she does eat. She has a friend in my speckled Sussex as they were chicks together.
