Thanks everyone for the comments. These guys have grown, and gotten a lot messier. They are staring to make the house smell, yuk! If they wouldn't be so messy they could stay in the house, but they just can't help playing in their water and food. So, they must move to the outside brooder house on Friday. They will have more room than what the Rubbermaid tub offers them, they will be able to make a mess, and they will be able to hear the sounds of the other ducks. I think they will like their new place.
