Let me start by saying that I have zero experience raising chicks. My wife and I have been wanting some laying hens so I did some research and found some barred rocks from a local guy. I picked up 8 of them and placed them into the brooder I had built (pictured). Everything appears fine at first, until I come back after about 10 minutes and find one of the chicks on its back away from the rest of the chicks and the heat lamp. A quick search and I figured out that I didn't have the thermometer in the right place directly under the heat source. It was topped out at over 120 degrees! I immediately hoist it up from probably 18 inches off the bottom of the brooder to about 2.5 feet which still has the temperature just below 100 degrees, but they seemed to be ok with that as you can see in the picture.
y concern is with the chick that flipped on its back. It will go with the group most of the time but will start panting and run away and look extremely lethargic. Recovers after a few minutes and usually sleeps, then goes back to the group. Rinse and repeat. Any idea what's going on with this chick? I've read that panting can mean numerous things, but it's hit and miss. It is the smallest chick in the bunch, so I'm not sure if that has anything to do with it or not. Any tips are greatly appreciated.
