Ducks are out!!

The mallards are 4 going on 5 weeks. I love them, but tired of cleaning their inside cage now twice a day. They are out in their pen. DH and I put them into their doghouse for about 10 minutes. Other than that they need to figure out how to get out of the elements. I am installing a tarp for shade. Today it was 78 tonight it's suppose to be 55. They should figure out if they should get in their dog house.
