I have 7 pekins. They stay for the most part in a 15x30 pen. I occasionally allow them to wander about. I recently built them a 6x6x 8 high house. The only time they use the house is to go in and eat and occasionally lay eggs. We are currently experiencing the effects of hurricane sandy here in ohio, it is about 40 degrees and pouring rain, and those ducks wont stay in the house. Yhey are huddled up in the middle of their pen. Is this normal for pekins? or are my ducks a little loony?
