I have had a problem rat ingress problem in my ayam coop. even with wire mesh laid inside and out they have gnawed through wood and pushed through where the mesh overlaps. Today i think i may have solved it! Aswell as the problem of what to do with all my aunts wine bottles lol. Yes i know its a little evil but so are they at times. I have filled the cavities with broken glass and pebbles the filled fully with expanding foam and re-covered with mesh. Im hoping glass and stone filled hard foam will at least give them a challenge? And may denture all together. Is this evil
, stupid
or justified 
Personally I don't think it will work but... I had a rat infested coop. I tried a lot of different things to no avail. I ended up using poison. I'm not advocating using poison only that it is what I resorted to. I moved the birds out of the infested coop into another coop and then began renovating it. I took the ceiling and walls out and when I did dozens of rats of all sizes poured out. I found several nests in the ceiling and walls. The rats even chewed through a 2x4 to get to the other side of the stud in the wall. I had seen some rats in our barn which is behind the coops. I bought some rat bait stations. I put the baited stations in pet carriers and put them on shelves so only the rats could get to them. I had noticed some tunnels around the coops that I assumed were made by the rats. I did not find any dead rats laying around from being poisoned so I assumed they went into their tunnels and died. They buried themselves. The rat bait stations have a little window above the bait so I can check it often. Also there is a partition inside that the rats have to go around to get to the bait. Good luck...
