Hi there! I have 4 chicks that are almost 9 weeks old and 3 mature hens. How do you handle the feed situation when you have chicks and hens? They are big enough and getting along with the hens enough for me to have them free range together when I'm home. My dilemma is the feed. The chicks leave the layer feed alone but my hens go right for the chick feed as soon as I open the chick's run up. Do I need to keep the younger ones separate until they are laying or is it ok for the hens to have some chick starter?
