depends where they live,we dont have racoons here but we sure do have desperate foxes,have heard from some BYCers that eagles have been their worst predator,just as well we only get pigeons and starlings.Lovely! One suggestion, invest in hardware cloth. Chicken wire keeps chickens in. That's it. I will not keep out a dog or a raccoon. Raccoons are the worst. Smart and dangerous. Otherwise, it is very very nice!

awesome setup larsocam,love the chicken cut outs on the doors.
very creative feeding and drink system,plus making use of free stuff!
