I've been using a Premier heat plate for 15 Cornish X and noticing it (I believe) is causing little burns at the point of their wings that stick out a bit on their backs for a couple of my chicks. I'm going to contact Premier too, but has anyone else had this issue? I don't think it's the height--I've had one end on close to the highest setting. Perhaps just b/c they have less feathering?
