Hi, I just got 15 Cornish Rock chicks that are, I estimate, 2-3 days old. They are in a plastic tub (50 Gallons) that I bought from Walmart. I bought a waterer and feeder tray from Tractor Supply as well that is in there. A heat lamp is attached to the tub and it is hanging approximately 12 inches away from the chicks. Can anyone please provide any suggestions or tips to reduce the mortality rates of these chicks? I wish to process them all, each of the 15. Thank you.
