Hi everyone ! Im fairly new here and a first time chicken mom I ordered chickens from McMurray hatchery and they arrived Thursday. All my chicks seemed healthy , I inspected each for blocked vents ,ect. No problems until today. About an hour ago I found one of my barred rock chicks dead and Im not sure why or what happened. My husband built a very nice brooder but it has been so cold and windy that I bought the chicks inside. I have a very large plastic tub with a heat lamp secured above at one end. I have been changing the feed and bedding daily, and refill the water several times a day. The temperature is where its supposed to be, been monitoring it regularly as well. Any thoughts, ideas or suggestions ? Thanks !
