First posting ever. I got 10 australorp chicks 1 week ago. Lost one 2 days later who failed to thrive. Now have one who is acting strange. Symptoms are: occassional panting, holding wings lower than usual. Doesn't seem to be as filled out as the other chicks. Also skin appears redder than the others, easier to see skin under fuzz. Eating and drinking the same as the other chicks. Temp 90 degrees under heat lamp, on pine shavings. Any ideas?
