Ok so today I went to my local feed store and someone recommended me to get chick starter for the first 8 weeks and then change to chick grower from 9 - 18 weeks but the problem is......that when I was looking for those 2 bags..... I couldn't find them! so then I saw this bag that said "Chick Starter/Grower" SOoooooooooooooooo wth am I supposed to do? can I feed them that for the first 18 weeks???? and another question..... can I feed my adult chickens "Layer feed" (including the roosters) for all their lifetime? I will sometimes give them snacks though
