I'm trying to figure out what I should be feeding my mixed flock. I have 2 laying hens who are 3 years old, some chicks that are about 12 weeks old that are both pullets and cockerels, and 2 little pullets that are about 7 weeks old. They all free range during the day. I've been feeding the youngest 2 Nutrena medicated chick starter, and the rest who are all in the same coop nutrena layer crumbles but after reading up on things today I've found out that I probably shouldn't be feeding them the layers. I also feed all but the youngest ones scratch as well. So I'm not sure exactly what I should be feeding them where it's such a mix of ages and genders. Thanks in advance for any advice I get.
