I have one chick about 3 weeks old which, for some reason, is fading away. He was once the most curious and energetic chick but is now very thin and weak. I bought these chicks off someone who I will now never buy from again. Of the 10 chicks I bought, I only have 3 left after 2 weeks. Is there any high energy or energy boosting foods I can give the chick? I have been giving them boiled egg but it doesn't seem to make a difference. Or any foods that will help the chick put weight back on again?
