I have three Partridge Rock babies in the brooder that are 7 days old. Two are fine, but one is lethargic, wobbly like no balance, breathes hard, sometimes has its mouth open, has wings spread, and when it peeps it sounds "hoarse"??? I know it sounds like its too hot, but I checked the temp it was fine. It has been eating and drinking, but just seems to be getting worse. Anyone have any suggestions???
