I have a six week old black and white crested polish chick that has stopped eating and drinking. She went from flying up and perching to greet me when I walked into our kitchen( we have our chicks inside untill they are six weeks to move outside into the coop) to now she isn’t eating or drinking and she seems really weak. She was doing this weird silent crow thing a couple weeks ago when I first brought her home but she was still eating and drinking( I’m gonna mention everything as we love her and I’m fairly new to this chicken thing and I want her taken care of) I’ve gotten nutridrench and given to her in a syringe. Ive rubbed her crop Incase she was backed up. She just has her feathers fluffed and sleeps she isn’t walking around. We don’t really have chicken vets around here and I’ve tried to reach out to the people we got her from but they haven’t responded. They are on purina medicate chick starter no other chicks are acting this way and I have separated her. One was sneezing randomly so I did put garlic and apple cider vinager in their water and that one stopped sneezing and I have continued with acv and garlic in their water just as prophylactic.
