We're going camping in a week or 2...and I'm worried about leaving the chickens. Every morning, I take food & water out to them. I get eggs out twice a day. So far, the most I've gotten in a day is 6...but we have 12 laying chickens and in a couple weeks we may be getting 12 eggs a day. So if we leave for a few days, is it okay if I put a ton of food and water out...and are the eggs okay to just kind of build up till we get back? Would they be okay to eat after sitting out there for 2 full days...possibly 3? There might be a lot of eggs. We don't have any neighbors to come help out.
