i bought some chick and they are now 6 wks old. we have had some cold wet weather and one seems to be sick. it is breathing hard and fast. its whole body moves when it breaths. it stays under the heat lamp when the rest of the chick go out. it is fluffed up mostly with it eyes closed. no runny anything. no swelling. normal poop. i brought it in the house and put it under a lamp in the dog crate and gave it some duramyacin and some chick grower with grit added to it. when i brought it into the house it stretched out under the heat lamp and casually ate and drank. does anyone know what this might be?
