Hi, I have a chick that is four week old that has trouble breathing. She was out with her mama, hatchmate and co-mama and I noticed she was not behaving as usual. She has trouble breathing and does not make any sound, not a peep when I caught her and took her away from mama. She has not eaten in the hour I have watched her, she still walks and fly fine but is not as active as usual. Could it be cocci or is it something stuck in her throat? I haven't seen any dropping from her yet which worries me too.
