How old(ish) will they be when they get their feathers? When do I have to stop worrying about them staying warm under a brooder light? How long do I feed starter to them? What do I feed them after they get off of the starter? I know that I've read that they are more hearty than baby chicks. How true is that? Because they grow faster? My kiddos are only a bit over a week old. I just don't want to jack up. edited because nobody deals with "sducklings" on here. ha ha! Type-o's are common with me.
