We have 2, 1 1/2 week old EEs that are getting big fast. We are going camping in 2 weeks and they are going to be moving outside then. The area thery are going in is in the coop, but in the storage section. We have used it multiple times for broodies, and we raised our ducks in there. I'm just wondering if by at 3 weeks, they can have shavings in the pen with them?
