I think that setup looks great! Question... Is that mushy feed in the plate? If so, based on my experience, I suggest you do a sniff test every 4-6 hours because I have found that when I wet out set feed like this it starts to go rancid very quickly, especially in warm brooders.I put both lamps in. One lower for the chicks. I divided the brooder as well...
