I was at the feed store yesterday. On the self with the poultry medications was a tub of Poultry Supplements. It was basically a Vitamin Pill in the form of a pellet. The instruction said to apply to the top of their feed in the morning. It claimed to be for helping week birds, birds that were moulting, before and after worming, during breeding, during laying or setting, or anytime a chicken needed a boost. Has anyone else seen this or used it? Does it sound like junk or something that may be useful on occasion?
