I have been raising quail for a year now. Never had any big illnesses or problems. I have hatched out five large batches (large to me) this current one being the largest- 67 chicks hatched. I had 18 Italians hatch and the rest jumbo brown. I have lost 14 babies, some sadly drown, even with marbles in their waterers (next time I will stick with my rabbit bottle waterers, so much better. However, the last 3 have been displaying some scary symptoms. They seem to be getting very week, even showing paralysis and wry neck symptoms. I am terrified they have mareks because of the symptoms. Is mareks for quail the same as for chickens? Or is it like the turkey strain? Or it's own strain? Do I have to worry about infecting my chicken flock? If it isn't mareks, what could it be? They have vitamins, apple cider vin and probiotics in their water, and got doses of antibiotic. They are eating chick starter. It has been cold here (in Florida) so maybe I can chalk up some losses to that. I haven't had this high of a chick mortality rate before. I have someone who wants to buy 20 of the jumbo browns once I can sex them, but now I am worried that I shouldn't sell any. Any advice?
