Everyone is different and so is the choice of how to deal with the rats. I have tried a lot of different things. I'll stick with the poison. The bait stations work great because nothing can get to the bait except the rats. I have tried different baits. some they wouldn't touch and another they loved. I haven't seen or found any evidence of rats in a long time and the baits haven't been touched and I haven't found any dead rats laying around and no dead birds or other critters. I don't put the bait stations anywhere near the chickens. Rats will travel a distance so the baits don't need to be around the birds. Different strokes for different folks.
Hens go broody when you don’t want them to… and won’t go broody when you do.
