The Three Lost Chickens

All of the chickens were in the pen with the cows, except three. I tried to catch them and put them in with the others but they refused to cooperate. I mean refused. They were over in the chicken coop. I gave them food and water in the coop but left it opened for them. They were not in there the next day, but I am guessing they were fine and finally made it to where the other chickens were since they were not in the coop anymore.
