Hi. I have heard that some people feed their chicks medicated chick starter right until they start laying. I'm horrified by this. The medicine as far as I can see is necessary only while the babies are young and vulnerable to disease (and even then, they would not be likely to get the chick disease if their living space is nice, warm, clean, dry and spacious. That disease is stress-induced from poor living conditions - same as people.) I always stopped feeding my chicks the chickstarter when the bag was finally empty (2-3 months of age) and then started them on grain & greens & some vitamins, etc. In 9 years I have never had a sick chicken. Some just keeled over land died at the age of 3, 4 or 5 years but were not sick beforehand. I guess they were just constitutionally weak from birth - same as humans. Does anyone have any comments. Thank you.
