I tried googling information. My chicks were originally on medicated started and i switched them to organic chick feed a couple of weeks ago. But I feel like it does not have anything to do with the food because i see them eating often. There is one in the bunch that is sort of fat and the other three I can clearly see and feel their keel bone. I am afraid that they are too thin but what could be the issue? Maybe they should be wormed? If I wormed them then what should I do. I do put ACV in their water several times a week. Maybe I should just be feeding them higher protein like boiled eggs?
