My local feed store only carries either a medicated poultry developer or laying pellets. I will be having chickens that are months apart and the tag on the bag says the developer is good to point of lay. I will have to go beyond that point because of the age difference in my 3 sets of chicks. The medication in the feed is bacitracin methylene disalicylate. The question is, when my hens start laying, are the eggs safe to eat with this medication?
