We have 5 sweet Brahma chickens. I currently have them in tractor which I move around with fencing, and currently they are cleaning up part of my garden. I also have netted dog run from amazon I move around with them which has a tarp over half for a bit of shelter. I purchased greenhouse plastic and was thinking to cover the run so they could have a dryer place when needed. I also have a barn- not sure if the tractor will fit in through the stall or not. But, my question is this— this Friday it’s going to rain and drop to the 40’s at night. They have feathered feet, and chickens don’t want to be wet and cold. So- go with the plastic on the run? Should I move their fencing to encourage them to go under shelter rather than into open garden? Should I try to move the tractor to barn and let them scratch in there on cold wet days? The barn also has a run-in on the back side- I could move their tractor over there. I’d rather have them up near me, but concerned about their wet feet and cold. I’ve added a few pics so you can see...
