Hi I recently added nesting boxes to my coop with decoy eggs. I just noticed one of my hens (that has not laid yet as far as I know) is in the nesting box and she appears to be panting. She stood up and there is an egg but I'm not sure if it is the decoy egg or a fresh egg.(since the decoy egg in the other box has been buried...) Is this panting normal? Should I be concerned?
