Oh my...I just read that you don't let chicks younger than 18 weeks eat layer feed. Mine were eating starter feed for about a month and about two weeks ago we put them all on layer feed because we let them out with the big girls. We were supplying both starter feed and layer feed but everyone was eating out of both so we decided to just let them all eat layer feed. I have three that are about 10 weeks old, the other babies should be right at 18 weeks. Should I seperate the three little ones for another 8 weeks and give them only starter feed? I hated keeping them confined, they love it out in the yard with the big girls.
