I am feeding DUMOR chick starter at 20% But also supplementing a little scrambled eggs a little Kale salad And I do add niacin in the form of nutritional yeast from my co-op even though DUMOR says they have niacin in the food. I do only have one heat lamp right now approximately 2 1/2 feet above their heads in there is an area away from the heat lamp but I’m cleaning their pen so frequently and getting them what I am wondering if they don’t have a chance to dry out because I’m trying to keep them so clean .. This duckling I did find lying felt cool. And right now it’s opening and shutting its mouth constantly as it’s kind of swimming in 5 inch deep water
