So I got two day old Ameraucana chicks from a local hatchery on Wednesday, March 28th so they’re now 1 week old. The white one is acting fine so does the other two a week older chicks except for this brown one. It looks like she keeps being lonely, hiding out in the corner, stretching her neck and opening her mouth (time to time) and her eyelids looks wide open.Also what may seem abnormal is that she’s sometimes shaking like mainly the abdomen part I see shaking when she’s laying down. I’ve raised chicks in the past, grew up living healthy and strong but I haven’t experienced one that’s acting so strange. I do provide fresh water and chick starter everyday, actually I change out the water every few hours when it gets dirty/foggy. I’ve did some research on these symptoms, and found out could be either coccidiosis (I don’t think so since she is pooping normally) or Marek’s Disease. If anyone out there reaching out saying I’m abusing animals or I’m not ready for chickens, just don’t answer, I’m doing the best I can to taking care of these chicks. I was thinking of providing Apple cider vinegar but I only have the Walmart Great Value brand that’s see through so I don’t think it would provide nutrients to kill fungus or other pathogens in their system. She is shaking a whole lot thought as she lays on her belly like she’s about to sleep. I don’t think she’s cold, I have the heat lamp not too high up so heat isn’t an issue.
