Exactly. A couple screws on each roost will solve that...or jam a wedge in between ends of roost and wall.Ok thanks! Two usually sleep underneath, but only recently they have been knocking it off. (last 3 days). Are they trying to get under it but they are too big?
Too close to something, hard to tell what it is.Also hard to tell from the pic but it looks like the one roost is right in front of a opening
