I will be picking up day old chicks Wed. I have gotten chicks from the feed store in the past. But not day old. What can I do to make sure their safe and well taken care of right from the start? Should I start with medicated feed? There will be 18-20: one waterer or two, one feeder or two? Beddingaper towels, pine shavings? I'm getting nervous and excited. I know it's not rocket science. Any info would be helpful.
