How important does everyone think it is to feed chicks the chick starter food until they are 18 weeks old like the directions on the bag say to do? I’ve opened up the chick section of the coop to the main section and now that they have access, I just don’t know how interested they will be to going back and forth between the two areas of the coop to get the chick food any more. My chicks are 8 weeks and 6 1/2 weeks old (two different clutches).
