Hello! I have a broody sitting on fertile eggs. I plan to let her raise them with the flock. I have a couple questions about the logistics. -I have always used Blue Seal feed, but they don’t make an unmedicated chick starter. Any recommendations? - When I transition the whole flock to starter feed and then back to layer feed in a few months, should I do it gradually or can I just switch them? - How should I prepare my coop for the babies? Should I do a very thorough clean right before they hatch?
