I have a new set of baby chicks, about 36 hours old. They were left in the incubator for 24 hours and now are in a brooding container, with a heat lamp (set at about 94 degrees), food and water. They all seem to be doing ok, eating and drinking, but there is one who seems to sleep more and is breathing harder than the others. No noticeable problems; no runny nose, no bloody poo...just breathing hard. Is there anything I can do for it? They have medicated food and probiotic water.
