I need some advice from all of the senior chicken keepers here. My SO's parents are in central Florida and in the potential edges (or path if it changes course) of hurricane Irma. They have never evacuated for a hurricane before so are very hesitant to do so now. But if it gets bad there they are in their 70s and in not really in shape to deal with attempting a late evacuation or to ride it out and pick up the pieces on their own. I have offered them to come up to our place in the upstate of SC. I know his mom is hesitant because she won't want to leave her chickens. I think she currently has around a dozen of them. I don't mind them bring the chickens as well if they have to, but I need advice as to how to house them in our backyard with our own 8 chickens. Her chickens are healthy, but being from a different area I am worried about the potential of them bringing along something that they are immune to but mine wouldn't be. We can easily rig up a run with some sort of shelter for them if need be, but what about when they leave, would that area be potentially hazardous to my chickens that free range my back yard during the day?
