I have two chicks who I am very worried about...Both chicks had yolk sacs still attached to them when they hatched, and one of the chicks is twitching. All my chicks were born about the same time and the 4 healthy ones are already in the brooder and very active. The one that has been twitching is still in the incubator, it hasn't even gotten on its feet and it hatched nearly 8-9 hours ago. He is just lying on his side..The other chick has something wrong with his umbilical cord I think. It looks almost like intestines coming out of his belly, and he had a very large yolk sac but it has dried. Can anyone help me? I really want to save these chicks if it is possible!
