Hi all! So my husband and I made this for our dog three years ago, and he has not spent a single night in it lol. It just sits in our backyard, and I was thinking that with some simple modifications, it would make a great duck house. I'm thinking of putting a latching door on the front so I can lock the babies up at night, since my dog sleeps in the house, and won't be outside to deter any nocturnal predators. I was also thinking of hinging the roof and making a side access door for easier cleaning. I'll also put windows,either on the roof or on the sides, lined with hardware cloth so nothing can reach in and hurt the babies. I also welcome any suggestions you may have on how to modify this dog house. And also, for now I have two ducklings coming to me later this week. Don't know the exact measurements of this dog house, but we made it for a 100lb dog. How many ducks do you think will fit comfortably in here overnight? Is it big enough for two?
