I have a one week old chick that is constantly breathing rapidly. It is eating and drinking fine and socializes well. It just gets tired quickly because of the breathing. I don't think it could be disease. The chick was hatched and brooding in the house - no drafts or cold. Could this be a case of immature lungs? And if it is, will it eventually get better? I don't really want to separate it from the others and cause more stress, it doesn't seem to be sick except for the breathing and it ccassionally pants. I don't think it's the temp of the heat lamp either because the other 12 chicks are just fine.
