HELP!!! I have rats, I hate rats, they are not in the coop's yet, but if they burrow anymore runways, one of my coops will fall into a sink hole. I did have a pest control company come and put a powder in the holes, assured that it would not hurt the chickens, and the rats have just burrowed more holes!!! any suggestions!!!! I would like to go as natural as possible, but at this point I am getting desperate. Here are the steps that are already done: 1. All waters are in the coop's that are locked up at night. 2. All of the food are in metal garbage cans. 3. There is nothing around the buildings for them to hide under, all underbrush is gone as is everything that was up against the building. We have 7 steers adjacent to the coops, we keep them cleaned, and know that not all grain is going to be eaten, and we need to have the water out for them. Please any suggestions would be greatly appreciated. Thank you!!!
