Our babies are in the pen for the first time today. They have always been in the coop so they're used to it so they are just going out for a few minutes and then running like mad back into the coop. But while they are going in and out, it is sprinkling off and on. If it starts raining will they stay in? I know that after a while, as they get more used to being outside, they will go out for more than a minute or two at a time.
