I need help on feeding and how much water I should make available for our chickens. I will get chicks first and feed them the mediated chick feed...but for how long??? I also read that around 17 weeks to give chickens some sort of laying feed? along with calcium? (ie clean eggs shells or can I buy this in case I dont have egg shells?) Grit? Do I keep giving them the laying feed or do I switch them at some point? What do the roosters eat? What "scraps" can I throw out to them or treats when they free range? I know corn and watermelon but that is all I know. So any food ideas I would love for you to share! Thanks!
