That will keep them out.
In putting on the roof bracing I found this in the attic at both ends under the peeks of the roof. I give up on it being an eagle’s nest and decided it was an overzealous sparrow trying to build a nest up at the peak. I took two 60 gallon trash bags and filled them over half way so I wouldn’t scatter it all over on my way to the chicken yard. Then I’m in the process of putting ½ inch hard wear cloth in and over all areas that they can get in. I got both ends of the house from inside and am ready to work on the north side. It will keep the sparrows out but the wasps and mud daubers will still get in.
