I have a 1-3 week old chick, and she stopped chirping awhile ago. She occasionally chirps if I go to pick her up. She sticks her head in the air and closes her eyes, opening and closing her beak. The others are all laying down sleeping, but she won't? Is there food stuck in her throat, or..? Update: I also hear a really quiet muffled sound, almost like when you lose your voice and can't speak.
