I need help. I'm losing chicks and I don't know why. I'm nervous its the cold, but I'm failing to see how.
So our brooding set-up is as follows. I have this contraption that is wood on the back and top, and wired left, right and front, with a fine mesh on bottom (lets the food and dropping fall but not the toesies). The heat lamp is in the front corner by its door, which is where I imagine the most cold comes in. Its located in my overbuilt garage that is insulated (even the garage door has insulation). Its chilly out there, but its not COLD. It was 40 degrees in the opposite corner from the heat lamp. There are bursts of colder air when the door opens and closes, but other than that, its more secure than Fort Knox so I know its not predators, its mommators.
Details on the chicks, they were born November 13-15, making them 7 weeks old today. They are 99% feathered, still some down on their little bellies.
Last night when I got home there was a dead chick. She was solid and I don't know if it was rigor or frozen (her body was solid but her neck/head moved around), she would have died in the 9-10 hours I was at work because she was alive that morning. This morning when I left for work there was another dead chick, again maybe 9-10 hours between when I saw it last and when I found it dead.
Food and water full, they did have a scoop of layer crumbles mixed in four scoops of chick starter because money is tight this week and I needed their food to stretch to payday.
I can't think of any other circumstances. Cars aren't started until the door is up, we don't sit in there with the car running, door open or not. I've been so fortunate on my fatalities and I am so lost on what I'm messing up here.
Of my 10 OEs, I'm down to 8, and I'm pretty sure 3 are cockrels.



Below is a picture of my brooder. The front and sides have been updated with hardware mesh so its not this open anymore. The light sits in the top right corner, inside the brooder.
