okay, chicken experts!! I have three 20 week old bantam cochins, 1 13 week old EE, and six 9week old chickens.  I believe we have removed all of the roos, time will tell.  I am currently feeding them starter feed with grit and de mixed in.  One of my banties has laid 2 eggs, and I would like to put them on layer feed.  Is it safe to feed it to everyone?  How do I feed oyster shell to just the layers??  I don't want the young ones to damage their kidneys.  What to do??
