my hen hatched out 5 chicks two days ago. 1 got squished, and 1 got left behind and got really cold I saved it warmed it up, and it's living with me inside right now. I went outside to check on mama and babies and one of the chicks was very lethargic not moving around much. I picked it up and it's very weak. I flipped it over and found that the tummy DIDNT form around the yolk at birth. It is now formed around and healed but that chick has a weird smell coming from it. It's smells like dog anal glands. I got water in it but it's not eating. I have it inside with the chick I reduced, and the rescued chick is doing perfectly fine but the lethargic one is not. I am not sure if maybe it's tired? Mama hasn't taken them inside at all today. It's breathing fine but it keeps closing its eyes
