It started couple hours ago. Usually all chick are happy and all, but this happened from nowhere
Can you tell us more about your chick - what do you feed, where is it housed, is the crop empty in the morning, can the chick poop, any symptoms like mucous, coughing, sneezing, runny nose or watery eyes?I dont know, but it has puffed its feathers and it seem to open its mouth to breathe
If you can answer the questions and supply some photos that would be helpful.
