My 9 month old Andalusian hen has been acting strongly the past 2 weeks. We hatched her from an egg and she grew up with a single brother, rooster. When she was 6 months she got separated from the rooster, because we didn't want chicks. When she moved in with the 10 older girls, she never really connected and was always by herself (All she wanted to do was hang out with the rooster...) I noticed about 2 weeks ago that her neck is always tucked into her shoulders and she never extends her neck. Along with that, she has been doing this weird thing where she opens the tip of her beak a little and pulls her head even farther into her shoulders. It only lasts about 2 seconds. Today she twisted her neck about 90 degrees the the side and opened the tip of her beak at the same time. She is also not eating or drinking (at least not when I'm around). When I held up a hand full of food she looked very interested, like she really wanted to eat, but just as she was about to peck the food she would stop. She never managed to actually eat the food. She isn't talking or making any of her usual chicken happy noises. It doesn't help either that It is the middle of the winter where I live, and she seems like she Is always cold. I am really worried because another chicken of mine had the same neck twisting, lazy, not moving symptoms and she ended up passing away. If anybody has any ideas Please help!!
