I know I have read on here about vitamins to give baby chicks in water, but I have looked for the thread for over an hour with no luck. I have some baby chicks that just are not growing very much and others that are only a week older and three times bigger. I have fed them the same and am not sure why the ones are so much smaller. I have had to seperate tham cause the bigger ones were starting to pick on the small ones and were stepping on them. I need to know what type and where can I buy them.....like at local feed store or where?
