Got my order of 17 chicks yesterday and knew that one baby wasn't going to make it thru the night, and he didn't. BUT the rest of them seemed just fine and eating and drinking. This morning there are two more that seem lethargic and not eating or drinking, just huddled up together. Temp is about 90-92 in the brooder, plenty of food and water available... What can I do about not losing MORE!! One is enough!
