I was skeptical about purchasing these BB houses at first because of the price and lack of reviews. So I’m writing to let everyone know they’re fantastic and worth every penny! I live in Jacksonville FL where we have eastern bluebirds. I’ve had them nest in my yard for over 10 years until we had a recent black crow attack on two sets of babies. So I went online in search of a predator free BB house. Success! Two sets of baby BB within a month. Just have patience because birds don’t really like change. They’re sort of like humans. They will use it once they adapt to it and I think they may actually like it better than the cedar ones you can buy in your local hardware store. Thank you Duncraft for another wonderful product! Don’t hesitate! Go ahead and get yourself one (or two like I did
