I have a 5-week old chick with her mother in their own coop with run. I've read that chicks are not supposed to eat layer feed until they're about 16 weeks old, so I've had mom and daughter on starter feed since hatching. Will I have to keep doing this for 11 more weeks? I would like to let the chick and mother free range with the others (22 total; 3 roosters, 19 hens), but I don't see how I could keep the chick from getting into their layer feed. Not sure how to handle this.
