We have 12 bantams and 7 standard breed chicks. One of the bantams always acts tired and recently started drooping on the left side only. It also shakes a lot despite the heat. We have isolated it. The chicks are in a clear plastic tote with pine chips and a brooder lamp. They have starter/grower feed and they have water with electrolyte. The bantams are not vaccinated for mareks, and I think the others are. They are almost 2 weeks old. Is this mareks or something else? If so, is it treatable? Please advise asap.
