A neighborhood chicken tragedy involving a coyote reminded me of an important coop building detail worth repeating:
Use galvanized poultry staples not staple gun staples to secure your 1/2 inch hardware cloth (and don’t use chicken wire–the gaps are so big that raccoons can reach right in and eat your poulrty through the wire). Poultry staples are nailed in with a hammer. I use a pair of needle nose pliers to hold the staple while I hammer it home. Regular staples rust and are not strong enough to keep out predators.
A last detail is to periodically inspect coops for possible weak points. I’m overdue for this. I’ve scared away a coyote twice now this year in our backyard (during the day!).
